Donald Trump has changed the party affiliation on his New York State voter registration to "unaffiliated," leaving the door open for a 2012 White House run.

"Mr. Trump has done that in order to preserve his right to run as an independent after the finale of his television show "The Apprentice" at the end of May," said Michael Cohen, a Special Counsel to Mr. Trump. "Something's he's stated over the past six months he might elect to do if, in fact, he's not satisfied with who the Republican candidate is and does not believe that that candidate can defeat Obama in 2012."

Most recently Trump was in the headlines for pulling out of his role as moderator of a GOP presidential debate in Iowa which only Newt Gingrich and Rick Santorum had committed to.
