Ad War Update: Ramping Up For Super Tuesday

In a spot that might qualify for a Hewitt Award nomination, Gingrich doubles down on his $2.50 gas promise:

His Super PAC emphasizes Gingrich's alleged ability to "take Obama apart" in a debate:

The Democratic PAC American Bridge exploits a sports rivalry in the Buckeye State:

… and targets Romney on the Blunt amendment: 

Total Super PAC spending this cycle now exceeds $64 million. Alex Burns zooms in on Ohio: 

Mitt Romney’s campaign and super PAC account for a big majority of the spending. The Romney campaign has shelled out $1,486,960, while Restore Our Future has put in $2,369,244. That totals nearly $3.9 million – massively more than any other single campaign or group has spent in the state. In fact, no other party in the race is in seven-figure territory yet, my always-reliable source tells me. The pro-Gingrich super PAC Winning Our Future has put in $736,044. Rick Santorum’s campaign has spent just $386,669, while his super PAC has put in $515,937. That means the pro-Romney forces have outspent the pro-Gingrich and pro-Santorum forces, combined, by more than two to one.
