This is the season of cultivation for people who might run for president in 2016.
It's a time to get to know donors, to get the public to know you on TV and social media, to visit big primary states, network with the activists and ideologues, produce a vanity book, polish a record, deflect personal baggage, take a stand, develop a world view and scout for advisers and political organizations that can power up a campaign team.
All this, for the season of harvest to come. And all while sounding coy about running.
The main players: For the Democrats, Vice President Joe Biden, former Secretary of State Hillary Rodham Clinton, New York Gov. Mario Cuomo and Maryland Gov. Martin O'Malley; and for the Republicans, former Florida Gov. Jeb Bush, New Jersey Gov. Chris Christie, Louisiana Gov. Bobby Jindal; Kentucky Sen. Rand Paul, Florida Sen. Marco Rubio, Wisconsin Rep. Paul Ryan and Wisconsin Gov. Scott Walker.
Here's a look at the hoops that people interested in the presidency must generally jump through to prepare for a campaign — whether they end up running or not — and who's doing what.
