If only Mitt Romney had Bill Clinton on his side.

The would-be Republican president stood on the podium beside the two-term White House Democrat at the Clinton Global Initiative on Tuesday, hoping a bit of stardust would sprinkle onto his own struggling candidacy.

Clinton is President Barack Obama's chief surrogate, and while the incumbent was due to speak later in the day at the CGI forum, Romney spoke at the event first, enjoying a warm introduction from the former commander-in-chief.

"If there is one thing we've learned in this election season, by the way, it is that a few words from Bill Clinton can do a man a lot of good," Romney quipped, to loud laughter and applause.

"All I've got to do now is wait a couple days for that bounce to happen."

Romney was referring to Clinton's speech which brought down the house early this month at the Democratic National Convention, where he had 15,000 enraptured Obama supporters in the palm of his hand.

Clinton had painstakingly outlined the case for Obama's second term, and it worked, with Obama enjoying a post-convention "bounce" in support -- a result that largely eluded Romney after the Republican convention the previous week.

Clinton, Romney said at the top of his remarks to the forum, "has devoted himself to lifting people around the world, and one of the best things that can happen to any cause, to any people, is to have Bill Clinton as its advocate."

Romney squares off against Obama in the presidential election November 6, exactly six weeks from Tuesday.
