An unexpected foreign crisis in the next seven months would pose a greater threat to President Obama's re-election than any of the Republican presidential candidates, including Mitt Romney, Vice President Joe Biden says.
"I don't think we'll be beaten by those candidates," Biden told a group 65 campaign donors Thursday night in Chicago.
"I think we'll be beaten - if we are - by something happening in the euro zone or something happening in the Gulf, which could be difficult for us, or this barrage of super PAC money. But even with that I feel good."
Biden and other top Obama campaign strategists have warned supporters that pro-Republican outside groups are planning to "carpet-bomb" the president with $400 million to $800 million in TV ads.
President Obama and Democrats have raised around $300 million for the 2012 campaign through February. The pro-Obama super PAC Priorities USA Action has raised only $2 million this year.
Biden said there are two reasons he's confident "we're going to win this election."
He called Obama the best candidate on the merits and said his campaign has "the best ground game that ever has occurred in the history of American politics."
"Thank God there's rooms like this I've been able to go in to all around the country," he said. "You guys are putting us in the game."
