President Obama, according to current and former West Wing officials, is more inclined to support Clinton’s candidacy. Despite her woes, he sees her as a more electable candidate and a more effective keeper of his policy legacy. He’s done everything but endorse her already, putting his vast fundraising network in the hands of Clinton’s super PAC allies. Two of Obama’s top White House aides, John Podesta and Jennifer Palmieri, are running Clinton’s campaign and report regularly to their West Wing old friends — including the president…

White House press secretary Josh Earnest told reporters on Monday that the president wouldn’t rule out making an endorsement in the primaries — and other West Wing officials told POLITICO that Obama has privately expressed a preference for Clinton as his successor, while keeping up the pretense of being undecided in public. (“I love ‘em both,” Obama said on NBC’s “Today Show” in February when asked who he would back.)

Clinton’s camp, hands full with the email controversy and a surprisingly stout challenge from independent Vermont Sen. Bernie Sanders, isn’t in a patient mood. Bill Clinton, according to a person who has spoken with the former president in the last couple of weeks, is “very agitated” by the possibility of a Biden candidacy and incensed at the press hype around a possible bid.

Hillary Clinton, Democrats in her orbit tell POLITICO, is less concerned — and several top Clinton campaign officials have told associates they think a Biden bid would energize what has been a fairly lackluster performance by the candidate this far.
