Crossroads is spending $5.3 million on the purchae for the ad, which also takes aim at the Obama claim that Mitt Romney's tax plan would mean a hike for the middle class.
The claim is based on a Tax Policy Center study which makes a wide variety of assumptions about Romney's policies and paints the outcome in a bad light. As many organizations have shown, it's particularly uncharitable towards the Romney plan.
Meanwhile, Priorities USA - the largest pro-Obama Super PAC - has come out with their own $4 million ad buy focused in the swing states of Colorado, Florida and Nevada. It's a Spanish-language ad campaign targeted at the Hispanic community.
We'll be seeing more and more of these big-spending SuperPACs putting money towards ads throughout September and October. Up until the conventions, very few "swing" voters have put much attention to the horserace. Up here in the D.C. media market, we've already started to see a deluge of TV ads due to Virginia's status as a swing state. It's going to be a sprint by both campaigns and their respective money machines to the finish.
