WASHINGTON (AP) - Just about everyone thinking about running for president is kicking it into gear now, slowpokes included.
For months, many prospective 2016 presidential candidates have been rubbing shoulders with donors, networking with party leaders, getting on TV and otherwise auditioning for the contest ahead, especially on the Republican side.
Their pace is picking up. A few are even admitting now what has been obvious for eons: They're interested in the presidency, even if they aren't ready to commit.
Others have avoided the usual pathways, for reasons that make sense to them even if their inscrutability exasperates others. "This is the time to show a little self-restraint," one of them, Jeb Bush, said back in November.
But that was then. He's shed some of that restraint now.
Hillary Rodham Clinton's inscrutability has bottlenecked the Democratic contest because several may decide not to run if she does. Asked in March, for the umpteenth time, about what she's going to do, she responded in her practiced coy fashion. "Give me your name and number," she cracked to a college student imploring her to run. "Obviously, thinking about all kinds of decisions."
But she's been picking up her activities, too. Ready for Hillary, a super PAC, has been busy on her behalf in early organizing. The question remains: When will Hillary be ready for Hillary?
What's clear is that springtime has arrived in 2016 presidential politics. Much more is going on since The Associated Press last took a broad look at who is doing what to get ready for a potential campaign.
Here's a summary of the main players.
For the Democrats, they are Vice President Joe Biden; Clinton, the former secretary of state; New York Gov. Andrew Cuomo; and Maryland Gov. Martin O'Malley.
For the Republicans: Bush, the former Florida governor; New Jersey Gov. Chris Christie; Texas Sen. Ted Cruz; Louisiana Gov. Bobby Jindal; Kentucky Sen. Rand Paul; Texas Gov. Rick Perry; Florida Sen. Marco Rubio; Wisconsin Rep. Paul Ryan; former Pennsylvania Sen. Rick Santorum; and Wisconsin Gov. Scott Walker.
NONDENIAL DENIAL: Cagey words that cloak presidential ambitions, none too convincingly.

Bush: "I can honestly tell you that I don't know what I'm going to do." - His standard disclaimer.
Christie: "I am enormously flattered that folks would talk about me in my party as someone who they think could be a candidate for president. But I am absolutely in - nowhere near that consideration process." - Jan. 9 news conference addressing the scandal over Fort Lee, N.J., traffic tie-ups.
Cruz: "My focus is entirely on the U.S. Senate." - His standard disclaimer
Jindal: "My honest answer is I don't know what I'm going to be doing in 2016." - February.

Rubio: "That's something that I'll consider later in this year, early next year." - March, NBC.

O'Malley: Yes, in December ended his year as finance chairman for the Democratic Governors Association and is one of the party's top fundraisers.
Bush: Yes, longtime connections on Wall Street and beyond. Flew to Las Vegas in March to meet GOP super donor Sheldon Adelson.

One of three prospective candidates who attended Mitt Romney's retreat with major party donors in Utah in June 2013.

Santorum: 2012 shoestring campaign was largely fueled by a super political action committee to which Republican donor Foster Friess gave more than $2 million.
Walker: Yes, addressed Republican Jewish Coalition at a Las Vegas gathering in March where main attraction was Adelson, who's looking where to place his bets in GOP field. Headlined 2013 fundraisers in New York and Connecticut.
NETWORK LIKE MAD: Taking their case to ideologues, activists and party heavyweights who hold great sway in nomination race.
Biden: And how. Plans to campaign in more than 100 races in the 2014 election. Meets regularly with former Senate colleagues and congressional Democrats. Gives keynote speeches at annual state Democratic Party dinners across the country. Making calls for House Democrats' campaign organization, assisting in recruitment of candidates. Campaigned for new Virginia Gov. Terry McAuliffe, Massachusetts Sen. Ed Markey. Speaks regularly to special interests.
Clinton: Steady presence now on speaking circuit, delivering paid speeches to industry groups and conferences and appearing before a number of groups with ties to the Democratic coalition.
Cuomo: Sparingly. Rarely leaves New York.
O'Malley: Yes, busy spring, with speeches to California Democratic state convention in March, Wisconsin Democrats in April and Massachusetts Democrats in May. Was Democratic governors' chairman for two years until December 2012.
Bush: Doing more this year. Recent travels to Tennessee, New Mexico, Nevada and Texas. Skipped Conservative Political Action Conference in March, after giving keynote speech to the influential group a year earlier.

Persistent courting of religious and economic conservatives in Texas and beyond. Pitched social conservative principles at Values Voter meeting in October. Addressed 2012 Republican National Convention before he was even elected to the Senate.
Jindal: Yes, big time and small time, far and wide. Addressed Conservative Political Action Conference in March, also in 2013. Made time for fundraiser for local sheriff in Michigan. Altogether, has spent much of his time during six years as governor on the road, talking to GOP and activist groups in other states, supporting Republican candidates and promoting his achievements. Created political action committee in March to help conservative candidates running for Congress.
Paul: Yes, plenty. Generated buzz and won symbolic straw poll at Conservative Political Action Conference in March. Campaigned in fall 2013 for GOP candidates in Virginia governor's race and Senate election in New Jersey. Met Michigan Republicans in September. Pitched social conservative principles at Values Voter meeting in October, and much more.
Perry: Yes, spoke at the past two Conservative Political Action Conferences as well as its regional meeting in St. Louis in September. Addressed conservative activists at a RedState Gathering in New Orleans in August, mistakenly saying he was in Florida. Job-pitching tour in various states helps make connections.
Rubio: Yes, conservative and party activists, focused lately on repairing tea party relationships strained over immigration. Well-received speech to Conservative Political Action Conference in March. In Virginia governor's race, campaigned for Republican Ken Cuccinelli, who lost.
Ryan: Yes, prime networker as 2012 vice presidential candidate; now helping fellow House members raise money.
Santorum: Opened 2014 with Texas speech to conservative think tank and followed with speech to Conservative Political Action Conference. Speeches around the country. His Christian-themed film company is his calling card with religious conservatives.
Walker: One of only a few 2016 prospects who spoke to Republican Jewish Coalition. Skipped the big Conservative Political Action Conference in March, appeared there last year. Campaigned for GOP in Virginia governor's race. Spoke to Michigan Republican Leadership Conference on Mackinac Island in September 2013.
HOG THE TV: Achieving national recognition by sermonizing on the Sunday news shows, or going for soft questions and easy laughs on late-night TV.
Biden: He's back. After being largely absent from the airwaves for more than a year, Biden has resumed frequent interviews, including a TV blitz the morning after the State of the Union and a CNN interview aboard an Amtrak train. He even dished on his skin care routine and his wife's oddball pranks during an interview with Rachael Ray to promote the health care law. But not a Sunday news show fixture.
Clinton: No. But late-night TV host Jimmy Kimmel interviewed her in March. Appeared with Obama on CBS' "60 Minutes" in January to talk about tenure as secretary of state; gave interview to Barbara Walters late in 2013.
Cuomo: No. Prefers radio.
O'Malley: Getting back in the swing. January 2014 Sunday news show appearance on CNN was first in months, followed by CBS in February.
Bush: Blanketed the five Sunday shows one day in March 2013 to plug his book on immigration, a few appearances other times.
Christie: Not so much since traffic scandal surfaced. Before that, liked to cut up on late-night TV. Four Sunday news shows after his 2013 re-election.
Cruz: Yes, several Sunday news show appearances already this year, plenty last year. Frequent guest on Fox News and CNN.
Jindal: No, only a couple of Sunday news show appearances since 2012 election.
Paul: Leader of the chattering pack with more than a dozen Sunday talk show appearances since 2012 election. Fast out of the 2014 gate with Jan. 5 appearance on ABC. Frequent guest on news networks, especially Fox.
Perry: Raising his profile lately, making several national TV appearances while starring in flood of media spots in California designed to persuade businesses based there to move to Texas. Only a few Sunday talk show appearances since 2012 election, including one in February with three other governors.
Rubio: Staying on par with most rivals in Sunday news show appearances. Blanketed all five Sunday shows one day in April 2013, before he dropped the subject of immigration; made several other appearances since. Frequent guest on news networks.
Ryan: Many Sunday news show appearances since 2012 election. Occasional guest on network news.
Santorum: Plugged Christmas movie on "The Colbert Report," Fox News, MSNBC and more. Radio, too. Teamed up with Democrat Howard Dean as sparring partners for debates on the air and with audiences.
Walker: Already on the Sunday news show scoreboard for 2014. Half dozen or so Sunday news show appearances since 2012 election. Also, Piers Morgan, Lou Dobbs, more national TV interviews.
ACTUALLY DO SOMETHING: For voters who want to support doers, not just talkers.
Biden: Leading Obama's review of federal job-training programs. Point man on gun control, which failed. Lots on foreign policy. Negotiated fiscal cliff deal. December 2013 trip to Asia put him front and center in regional dispute over China's new air defense zone.
Clinton: Record as secretary of state, senator and first lady. Recent initiatives to help children's health and education and status of women.
Cuomo: 2014 budget proposal calls for tax cuts for businesses, homeowners and renters. In 2013, pushed through nation's first gun-control law after the Newtown, Conn., school massacre. Led New York's effort to legalize same-sex marriage in 2011. Minimum wage boost, on-time budgets, teacher standards.
O'Malley: Toughened gun laws, repealed death penalty, saw voters approve gay marriage after he got behind legislation to approve it, set up a framework to develop offshore wind power, won legislative approval in April of minimum wage increase, a 2014 priority.
Bush: As Florida governor, revamped state educational system, cut taxes, managed state through hurricanes.
Christie: Won November 2013 re-election, becoming first Republican to earn more than 50 percent of New Jersey vote in quarter-century. Led state's response to Superstorm Sandy. Agreed to expand state's Medicaid program under the new health law while some other Republican governors have refused to do so. Vetoed a bill that would have sanctioned gay marriage, but declined to appeal a court ruling that legalized it.
Cruz: Leading force in dispute that partly shut the government, 21-hour Senate speech against Obama's health law. Argued before U.S. Supreme Court nine times, with eight of those coming while he was Texas' longest-serving solicitor general, between 2003 and 2008.
Jindal: Privatized much of Louisiana's Medicaid program, shrank public hospital system, signed statewide voucher program that covers private school tuition for certain students. Signed abortion restrictions, fought liberalization of adoption law, making it impossible for gay couples to adopt jointly. Hurricane and Gulf oil spill disaster response.
Paul: One-man, nearly 13-hour Senate filibuster to protest drone policy put him at forefront of civil liberties debate.
Perry: "Texas Miracle" job-creation boom has seen state create a third of the net new jobs nationwide over last decade, although Texas has disproportionately high percentage of hourly workers earning minimum wage or less. Helped muscle through new abortion restrictions.
Rubio: Broker of Senate immigration overhaul, though he's gone quiet on the issue. Early leader of effort to link financing of health care law to government shutdown. Working with anti-abortion groups on Senate version of bill that would ban abortions after 20 weeks.
Ryan: Negotiated December 2013 bipartisan budget deal that scaled back across-the-board spending cuts, drawing contrast with potential rivals who opposed it. Budget-hawk record to be judged on. Emerging as influential moderate on immigration.
Santorum: Making Christian-themed, family-friendly movies at the moment; record from Senate days.
Walker: Curbs on public service unions became national flashpoint, but he won the effort - and the recall election that followed.
TAKE A NATIONAL STAND: Effective state governance is nice but leaders must build national stature on issues of the day.
Biden: Eclectic. Guns, violence against women, gay rights, veterans.
Clinton: Eclectic. 2013 speeches focused on the economy, housing, opportunities for women, voting rights.
Cuomo: Environmentalists nationally and the energy industry are closely watching his pending decision whether to allow fracking in upstate New York counties near the Pennsylvania line.
O'Malley: The liberal checklist: more spending on education, infrastructure, transportation; supports same-sex marriage, immigration reform, repealing death penalty, pushes environmental protections.
Bush: Education, immigration, economy.
Christie: Moderate on the reach and functions of government; bipartisanship.
Cruz: Anti-Obama's health care law, pushes broader tea party agenda.
Jindal: A record of privatization to show he means government should be trimmed, happy to carry a social conservative banner.
Paul: Tea party plus. Fiscal conservative, criticizes surveillance state. Praised Supreme Court gay marriage ruling as one that avoids "culture war." Health law scold. Joining in 2014 with liberal lawmakers and others in effort to roll back some mandatory minimum sentences and give judges more flexibility in fitting punishment to crime.
Perry: Prominent voice on conservative issues since before the birth of the tea party. Wants to ban all abortion in Texas, relax environmental regulations, boost states' rights; opposes gay marriage.
Rubio: 2014 initiative on poverty calls for federal wage supplements for some low-wage workers instead of earned income tax credit. Economy, abortion, tea party fiscal conservatism; immigration liberalization if he decides to get back to it. Another voice against health care law.
Ryan: Cutting spending, taking on entitlements, rolling back Obama's health law. Anti-poverty initiative this year.
Santorum: Social conservative activism goes way back. Focus on blue-collar economic opportunity.
Walker: Fiscal stewardship, from a GOP point of view. Tough guy against the unions and liberal defenders of the status quo. Says GOP in Congress is the party of no.
BAGGAGE TO CHECK: It's never too early to deal with skeletons in the closet; rivals will be rattling them soon enough.
Biden: Flubs, fibs, age. Deflection: "I am who I am." Saddled by Obama's low approval ratings.
Clinton: Benghazi, Libya; polarizing when political, age. GOP wants to pin blame on her for vulnerability of U.S. diplomatic mission in Libya that came under deadly attack in 2012. In long-confidential documents from Bill Clinton's administration, advisers urged her to "be real" and "humanize" herself, revealing concerns about her authenticity as a public figure.
Cuomo: New York economy is dragging, his poll numbers have sunk, went through public and bitter divorce with Kerry Kennedy, daughter of late Sen. Robert Kennedy, in 2005.
O'Malley: State-run health insurance exchange website was an expensive bust, prompting officials to make an embarrassing switch in April to one based on Connecticut's. Contraband- and drug-smuggling scheme at state-run Baltimore City Detention Center that resulted in 44 people being indicted has state lawmakers looking to make reforms. Has record of raising taxes that could be challenged by less liberal Democrats, never mind Republicans.
Bush: The Bush factor. Does the country want a Bush dynasty after presidents George H. W. and George W.? Some education and immigration positions are out of step with the right.
Christie: If you have to declare "I am not a bully," you've got a problem. Apologized in January 2014 for highway lane closures apparently ordered by his aides as retribution against a mayor who did not endorse him for re-election. Also fired his deputy chief of staff and denied knowledge of the machinations. Episode deepened questions about what Christie, or those around him, will do to win, and contributed to a significant drop in his poll standings. Investigations continue.
Cruz: Reputation as a hotheaded upstart, also part of his appeal. Polarizing within his party. Also comes with birther baggage: Questions have been raised in some quarters about his constitutional standing to become president because of his birth in Canada, to a Cuban father and American mother. Deflection: Promised last summer to renounce Canadian citizenship, but hasn't.
Jindal: Ambitious plan to replace state's personal and corporate taxes with higher sales taxes flopped, delivered dud of a speech when given juicy platform of responding to Obama's first presidential address to Congress in 2009. Deflection: Poking fun at himself. Jindal administration's award of a $200 million Medicaid contract is under investigation by state and federal grand juries.
Paul: Dear old dad: Must move beyond Ron Paul's fringe reputation. Bridge-burning in Congress endears him to tea party, could bite him otherwise. Deflection: GOP outreach to minorities. The Washington Times canceled his column after he was found to have used passages from other people in his speeches and writings as if they were his own. Deflection: Promising proper citations and footnotes for his pronouncements "if it will make people leave me the hell alone."
Perry: "Oops!" Memories of his stumbling 2012 campaign, a quick progression from a front-runner to flameout. Deflection: Poked fun at himself for forgetting in a GOP debate one of the federal departments he would close as president, Energy.
Rubio: Rift with tea party constituency on immigration, "a real trial for me." Deflection: Go aggressive on a matter of common ground, which he did in pledging to take apart the health law. And stop talking about immigration. Response to Obama's 2013 State of the Union speech was remembered only for his clumsy reach for water. Deflection: Made fun of himself.
Ryan: Budget axe cuts both ways - catnip to conservatives but people want their Medicare. Carries stigma of 2012 election loss as running mate. Tea party not happy with his late 2013 budget deal. Comments in March about cultural "tailspin" in inner cities struck some as veiled racism. Deflection: Called his remark "inarticulate."
Santorum: Overshadowed by newer conservative figures. Deflection: Being overshadowed means being an underdog, and he can thrive at that. Feisty 2012 campaign became the biggest threat to Romney's march to the nomination.
Walker: Some things that give him huge appeal with GOP conservatives - taking on unions, most notably - would whip up Democratic critics in general election. Wisconsin has lagged in job creation. Release of emails in February shed light on criminal investigation into whether Walker's aides were illegally doing campaign work for the 2010 governor's election while being paid as county employees. Walker, then a county executive, wasn't charged but the episode has proved a distraction.
RUN SHADOW CAMPAIGN: One way to run without running is to have a political action committee to promote ideas or other candidates for office, or to hire advisers who can switch to a campaign when the time comes.
Biden: Constrained by his current job, but tapped longtime adviser and former lobbyist Steve Ricchetti to be his new chief of staff; maintains close contact with political advisers past and present.
Clinton: Ready for Hillary super PAC set up by supporters is laying groundwork, so are others. Several old Clinton hands are advising the group, including Craig T. Smith and Harold Ickes.
Cuomo: Overshadowed by Clinton's shadow campaign. Considered a likely contender if Clinton ends up not running.
O'Malley: Set up a PAC called O'Say Can You See and hired two people for fundraising and communications.
Bush: He's a Bush, so he's got connections. Sally Bradshaw, chief of staff when he was governor, is his go-to political person.
Christie: Republican Governors Association chairmanship allows him to grow his national profile with voters and party officials with regular travel and key appearances. Began building broad coalition of donors through his national fundraising tour in spring 2013. But the shadow of the traffic scandal still hangs over his shadow campaign.
Cruz: Has leadership PAC, Jobs Growth and Economic Freedom. Has been one of the largest beneficiaries of Jim DeMint's Senate Conservatives Fund and has gotten millions of dollars and grassroots logistical support from the Club for Growth, FreedomWorks and Ending Spending PAC. Heritage Action PAC helped sponsor Cruz's summer anti-health-law trip around Texas and country.
Jindal: Created Washington-based nonprofit, America Next, in October 2013 to push policy ideas nationally. For executive director, tapped Jill Neunaber, who worked on Romney's presidential campaign in Iowa and New Hampshire. In March created PAC to help conservative candidates.
Paul: Has formidable leadership PAC called Rand PAC, has maintained ties to father's political network in early primary states and benefits from strong tea party support.
Perry: Created Americans for Economic Freedom PAC in fall 2013 to raise his profile again, help him test the waters and broadcast ads promoting Republican leadership around the country. Group used more than $200,000 left over from the PAC that raised millions for his 2012 campaign.
Rubio: Expects to begin more aggressive travel to early voting states in 2014. Reclaim America PAC led by former deputy chief of staff, Terry Sullivan, veteran of South Carolina politics, expected to be active behind GOP candidates across country in 2014 midterms.
Ryan: His Prosperity Action PAC.
Santorum: Keeps in touch with chief supporters of his winning 2012 Iowa caucus campaign, giving him a leg up on a campaign organization in that state.
Walker: Consults with top Republican governor strategists such as Phil Musser and Nick Ayers.
GET WITH IT ON SOCIAL MEDIA: A must for spreading ideas, poking competitors, raising money, organizing events and showing a personal side, though often a very canned version.
Biden: Not active on Facebook, occasional contributor to his office's vigorous Twitter account.
Clinton: More than 1 million followers on Twitter, her preferred social media outlet.
Cuomo: Few if any personal tweets; Facebook also generated primarily by staff.
O'Malley: On Twitter, standard governor's fare but promotes rare appearances by his Celtic rock band, O'Malley's March, for which he sings and plays guitar, banjo and tin whistle. On Facebook, his PAC-generated page is more active than official governor's account.
Bush: Tweets and posts many Wall Street Journal stories, education thoughts and some Bush family doings.
Christie: More engaged in Twitter ("It was great to be able to visit with the owners of Rossi's Rent-A-Rama in Ortley today.") than Facebook.
Cruz: Active on Facebook and Twitter, much content is pumped out by staff.
Jindal: Active on Twitter and on Facebook, where he lists among favorite books, "John Henry Newman: A Biography," about recently canonized British cardinal and sage. Also favors James Bond movies.
Paul: Aggressive. Bragged on Twitter in June that he'd attracted more than 1 million likes for his Facebook page, where he lists his own books as his favorites.
Perry: Active. One popular tweet was accidental - from his pocket, he said - and consisted of "I." Followers jumped in to complete his sentence. One offered: "I ... really like Obamacare." (He doesn't.) Facebook appears staff-generated.
Rubio: Aggressive, with large followings, appears to make personal use of Twitter more than staff-generated Facebook. Takes lots of shots at the health law. On Facebook, lists "Pulp Fiction" movie and "The Tudors" historical fiction TV series among favorites.
Ryan: King of Facebook among potential rivals in both parties, with nearly 4.9 million likes. Seeks $10 donations for "Team Ryan" bumper stickers for his PAC and kisses a fish. Posts photo of Obama with his feet up on Oval Office desk. Commanding presence on Twitter, too, via an account associated with his PAC and another as congressman.
Santorum: Active on Twitter and Facebook, where he relentlessly plugged his new movie and goes after the health law.
Walker: Posts vigorously on Facebook and on his Twitter accounts. Many exclamation points. "Glad USDA is keeping cranberries on school menus. I drink several bottles of cranberry juice each day!" And, "Green Bay Packers signing Julius Peppers to a 3-year deal is HUGE!" Promotes policy achievements and his TV appearances, reflects on sports, pokes Obama.
