joining me is tallahassee bureau chief for the miami herald and gary segora, professor of political scienceat stanford. romney went after gingrich for that spanish language radio ad that the gingrich camp has since pulled down. he had called romney antiimmigrant. let's look. >> is he still the most antiimmigrant candidate? >> i think of the four of us, yes. >> go ahead, governor. >> that's simply inexcusable and actually, senator marco rubio came to my defense and said it was inexcusable. i'm not antiimmigrant. my father was born in mexico. my wife's father was born in wales. the idea is repulsive. don't use a term like that. >> we were talking about this earlier, did seem that romney came loaded for bare to that debate. gingrich seemed to be disengage ed a lot of the time. what's your take on that? >> well, it was clear romney was prepared to attack gingrich on this. it's been an interesting issue to watch. because while romney and gingrich as far as i can tell, they don't have a dramatically different approach to how they will handle this, gingrich has been less attacked by the democrats
