Pro-Romney group to spend $12M on swing-state ads

If you live in a swing state such as Colorado or Virginia, get ready for more presidential campaign ads with a pro-Mitt Romney message.

Restore Our Future, the super PAC supporting the GOP nominee, is spending $12 million on ads that will reportedly blanket the airwaves in states that are almost all battlegrounds. The New York Timesreports the buy is the group's "most aggressive and expensive push yet" in the campaign's ad wars.

The ads will run in Colorado, Florida, Iowa, Nevada, North Carolina, Virginia and Wisconsin -- all swing states -- plus Michigan, a firm that tracks political advertising told The Times.

Public opinion polls show the race is tightest in many of those battlegrounds where the ads will air, starting Tuesday. An average of 3 percentage points or less separate President Obama and Romney in Virginia, Florida, Wisconsin, Nevada and Colorado, according to polling compiled by RealClearPolitics.

Romney was born in Michigan. Obama is leading by an average of 5 points, RealClearPolitics says.
