Celebrity endorsements in the 2012 presidential campaign

Will Ferrell 

The comedy actor is famous for his hilarious portrayals of former President George W. Bush, but Ferrell might not be so quick to mock President Obama. The actor stopped by the White House press room in October while in Washington to receive the Mark Twain Prize for American Humor. On the red carpet for the event, Ferrell told reporters that he "most definitely" wants Obama to win reelection.
