Bill Burton, the head of the pro-Obama Super PAC called Priorities USA, on Monday blasted Republican presidential candidate Mitt Romney, saying he won elections by drowning his opponents in money.

"I think Mitt Romney counts on the fact that he can win elections by vastly outspending his opponents," Burton said on MSNBC.

He denied that recent fundraising solicitations by the Obama campaign threatened to alienate voters.

"I think the smart folks who are sending those things out know what they're doing," Burton said.

"What they're trying to do, I imagine, is engage, you know, a large number of the folks who support President Obama but have been sitting on the sidelines," he said. "They look at Mitt Romney and say, 'Is this clown really going to beat President Obama?' and the answer is 'Well, maybe, if he has four or five times as much money as the president, then yes, he may well have a chance at winning in November.'"

Politico has reported that pro-Republican groups like the U.S. Chamber of Commerce, Crossroads GPS and Americans For Prosperity plan to spend approximately $1 billion on November’s elections. The Romney campaign and Republican National Committee plan to raise an additional $800 million.
