President Barack Obama’s top advisers are quietly laying the groundwork for the 2012 reelection campaign, which is likely to be run out of Chicago and managed by White House deputy chief of staff Jim Messina, according to Democrats familiar with the discussions.

The planning for now consists entirely of private conversations, with Obama aides at all levels indulging occasionally in closed-door 2012 discussions while focusing ferociously on the midterm elections and health care reform, the Democratic sources said. “The gathering storm is the 2010 elections,” one top official said.

But the sources said Obama has given every sign of planning to run again and wants the next campaign to resemble the highly successful 2008 effort.

David Axelrod, White House senior adviser, may leave the West Wing to rejoin his family in Chicago and reprise his role as Obama’s muse, overseeing the campaign’s tone, themes, messages and advertising, the sources said.

David Plouffe, the Obama for America campaign manager, described by one friend as "the father of all this," will be a central player in the reelect, perhaps as an outside adviser.

"The conversations are beginning, but decisions haven't been made," a top official said. "If you look at David Plouffe's stepped-up level of activity with the political organization [as an outside adviser on the 2010 races], that is obviously the beginning of the process."

Anita Dunn, former White House communications director, will be intimately involved, too. Brad Woodhouse, the Democratic National Committee’s communications director, has rising stock and is a logical choice to be communications director for the reelection campaign, the sources said.

White House press secretary Robert Gibbs, White House communications director Dan Pfeiffer and senior adviser Valerie Jarrett are likely to remain at the president’s side in Washington, while exercising major influence over the campaign. Pfeiffer, communications director of the last campaign and always a trusted insider, has a higher public profile every day.

Other central figures are likely to be DNC Executive Director Jennifer O'Malley Dillon; her husband, Patrick Dillon, who is deputy White House political director and is likely to bring his extensive gubernatorial contacts to Chicago; Mitch Stewart, executive director of the DNC's Organizing for America; Jon Carson, national field director of Obama for America; and White House political director Patrick Gaspard.

The DNC sees Republican challengers ramping up earlier than ever and has decided to begin defining potential opponents early. Operatives are already assembling research and drafting unflattering narratives to push about the leading possible 2012 candidates.
