McCain: Biden 'ready to gaffe'

With Sarah Palin under assault for a series of interview flubs, John McCain's campaign is trying to even the score before tonight's vice presidential debate with a web video highlighting Joe Biden's penchant for gaffes.

"What might Joe Biden say at tonight's debate?" the announcer asks. "Anything's possible."

The ad shows a TV screen with Biden saying, "I think I probably have a much higher I.Q. than you do....What am I talking about?"

"We know he has impeccable tact," the announcer says.

Biden is shown saying in 2006 in a quip captured in a YouTube video that resurfaced during the Democratic primaries, "You cannot go to a 7-Eleven or a Dunkin' Donuts, unless you have a slight Indian accent. I'm not joking. ...What am I talking about?"

"Maybe he'll send Hillary in his place?" the announcer says.

"Hillary Clinton is as qualified or more qualified than I am," Biden is shown saying in New Hampshire last month. "Might have been a better pick than me....What am I talking about?"

"And what might he say about his vote to raise taxes on those making just $42,000 a year?" the announcer asks again.

"It's time to be patriotic Kate, time to jump in, time to be part of the deal," Biden is shown saying in a TV interview.

"We know he'd never embarrass himself," the announcer continues.

"Stand up Chuck. Let them see you! Oh, God love you, what am I talking about?" Biden is shown saying at a campaign event last month to a man in a wheelchair.

"Ready to gaffe? Yes. Ready to lead? No," the announcer concludes.
