After a nice introduction from Bill Clinton at the Clinton Global Initiative, Republican presidential candidate Mitt Romney suggested that the former president is responsible for the current White House leader's post-convention lead in polls. 

"If there's one thing in this election season by the way, it's that a few words from Bill Clinton can do a man a lot of good," Romney joked. "Now all I have to do is wait a couple of days for that bounce."

It was a compliment to Clinton, but also a bit of a jab at President Obama, suggesting that the incumbent's bounce has more to do with the ex-president's words than with his own campaign. 

Romney's campaign dismissed polls after the Democratic convention as a "sugar high," and the last Washington Post-ABC News poll found the candidates tied among likely voters. But a new Post poll gives Obama an eight-point lead in Ohio.
