Obama camp calls Romney PAC TV ads in PA 'desperate'

Restore Our Future, a political action committee run by supporters of Republican presidential nominee Mitt Romney, is putting $2 million into television commercials in Pennsylvania in the last week of the race, with more than half of the money going to the Philadelphia market.  President Obama will also start running ads in Pennsylvania, campaign manager Jim Messina said in a conference call with reporters Monday morning.

"They understand that they're not going to win in Ohio so now they're getting desperate," Messina said. "They are not close in Pennsylvania. We are going to win Pennsylvania."

David Axelrod, Obama's senior campaign adviser, said the Democratic ads are a "precaution."

"We're not going to surrender any state to them in terms of airways," Axelrod said. "Make no mistake about it. This isn't a sign of strength on their part. It's a sign of weakness. They're looking for a way out."
