Celebs endorse presidential candidates

As Arizona gets ready to host tonight's Republican presidential debate, some of the candidates are getting celebrity support.

ABC News has a slideshow of who's backing who in Democracy 2012.

Here are a few of them.

Donald Trump has endorsed Mitt Romney, saying, "He's smart, he's sharp, he's not going to allow bad things to continue to happen to this country that we all love."

Eva Longoria is a huge supporter of president Obama, and has signed on to be one of 35 ambassadors for his re-election campaign.

Chuck Norris is putting his trust in Newt Gingrich, saying, "We need a veteran of political war who has already fought Goliath."

And, Arizona's own Michelle Branch is standing up for Ron Paul.

When fellow singer Kelly Clarkson announced her support of Paul, Branch tweeted, "I wholeheartedly agree!"
