MoveOn.org released a new ad which features Mitt Romney and Paul Ryan literally stepping on the middle class. The ad will air on cable news channels in Tampa this week along with the GOP convention, reports Politico. The ad shows Romney and Ryan lookalikes actually stepping on middle class Americans, including children and seniors, as they walk to the convention stage and accept the nomination. “Mr. Chairman, fellow members of the one percent, we thank you for your generous support,” Romney says in the ad.
