Thus far, Rick Santorum's super PAC ad campaign hasn't attacked his Republican opponents
Fox's Ed Henry
reports Rick Santorum's super PAC has nearly doubled it's Michigan media buy, purchasing $600,000 in ad time on top of the nearly $700,000 it
announced last week. That will put Santorum's total Michigan buy over the campaign's final two weeks at rough parity with Mitt Romney, but Romney's super PAC has been on the air in the state
since January 24 and had already spent nearly $1 million by mid-February.
The news comes as three new polls show a tight race in Michigan. Although PPP's latest survey shows a small Santorum lead, We Ask America has the race tied and a poll released this morning by Mitchell Research has Romney ahead. FiveThirtyEight's latest forecast gives Romney a 51 percent chance of victory.
In recent days, Romney's super PAC has focused its ad campaign on attacks on Santorum. Ron Paul—who has emerged as an unlikely ally of Mitt Romney in state after state—is launching a new statewide ad campaign in Michigan attacking Rick Santorum as well. Although their ads are different, the message is the same: attacking Rick Santorum's fiscal record from the right.
