Newt Gingrich already has ads running in South Carolina attacking Mitt Romney as "pro-abortion," and his Super PAC is planning to drop a socialist neutron bomb on Romney's career at Bain Capital, thanks to a large donation from a viciously anti-labor casino magnate billionaire. And here's yet another, lighter attack: A compliation of Mitt Romney saying ludicrous things. (Newt Gingrich, see, has never said anything ludicrous in his life.) Who can resist? Especially since it includes the "Who Let the Dogs Out" MLK Day moment of 2008, the pinnacle of Romney's career.
