The newest buzz-generating character on the campaign trail is "Rombo," courtesy of a Rick Santorum ad. In it, a Mitt Romeny lookalike tries to spray Santorum with a mud gun only to have it backfire on his white shirt. Romney's "negative attack machine is back, on full throttle," says the narrator of the ad, which has hit the airwaves in Michigan. "It is not only an entertaining and amusing commercial, but potentially effective," adds Andrew Belonsky at Death and Taxes. (Romney laughed off the ad today on Fox News, notes Politico.)
The super PAC backing Romney, meanwhile, has released an ad of its own depicting Santorum as a big-spending Washington insider. "It's a familiar pattern," writes Michael A. Memoli at the Los Angeles Times. "As another 'anti-Romney' comes to the surface, the group Restore Our Future and other Romney surrogates go on the attack." It, too, is airing in Michigan, where Romney is banking on a big win. (More Rick Santorum 2012 stories.)
