One of Obama's biggest endorsements from 2008, former Republican Secretary of State Colin Powell, is declining to support him again. Or at least he won't endorse him just yet:

Retired Gen. Colin Powell is not prepared to back President Barack Obama in the 2012 presidential campaign.The former secretary of state under former President George W. Bush endorsed then-candidate Obama in the 2008 election, but said Sunday on CNN's "State of the Union" that he will wait to make a decision on whom to support in the next presidential election.

Given how Powell is reticent to be overly partisan this isn't all that surprising. However, as Beltway establishment weathervane this doesn't bode well for the President.
