All Romney has to do is repeat what he did to Gingrich in Florida and this race is over.
Besides, if Ronmey dares go 'out of character' and says anything the least bit accurate about Bonzo, the media will beat him to death and release instant polls showing how 'unlikeable' Mitt is. It will be like when big, bad mean Ricky Lazio attacked that poor, sweet little Hitlery girl all over again.
