Errr, they are?

Via Politico:

Bill Burton of pro-Obama super PAC Priorities USA said on Monday that millions of dollars worth of ads attacking Mitt Romney tenure at Bain Capital are “clearly working.”

“We’re just now in the middle of $10 million we spent on television ads about Mitt Romney’s time in the private sector, and they’re clearly starting to work,” Burton said on MSNBC’s “NOW with Alex Wagner.” “If you look at any of the numbers out there, any public polling or focus groups, they’re clearly working.”

Burton said that fundraising has “picked up considerably” for Priorities USA. But he said he still expects that Romney and his supporters will outspend Obama and his groups. Burton also tried to explain the rather desperate fundraising solicitations in recent days from the Obama camp.
