A new ad from the Democratic National Committee takes aim at who presumably it believes is the strongest GOP candidate for president (newspaper endorsement or not) -- Mitt Romney -- with a faux movie trailer. The ad, posted online last night and running in six battleground-state markets (D.C., Albuquerque, Raleigh, Columbus, Pittsburgh, and Milwaukee), is titled "Mitt v. Mitt," meaning that yes, it deals with Romney's flip-flops, the most tired tried and true way of attacking the former Massachusetts governor. Despite covering the beaten trial of Romney's position changes, the ad redeems itself somewhat with its campy, overly dramatic parody of movie trailers. ("From the creator of I'm Running for Office for Pete's Sake, comes the story of two men trapped in one body...") The 30-second spot is actually a plug for a much longer video at MittvMitt.com, which again humorously tries to go over all of Mitt Romney's flip-flops in four minutes with Jay Leno and Conan O'Brien clips spliced in for good measure. And really, when they're all culled together, it does seem like a lot. The longer DNC ad argues that Romney's changed positions on the economic stimulus, on abortion, on the goodness of Reagan, on global warming, on a no-new-tax pledge, on... you get the idea. Mike Allen notes that the Democratic party will "hold events to watch the video and put Mitt Romney's fight against himself on full display for voters in key states," according to one DNC official. The longer video is below.
