Hotsheet Live: Can Romney survive a loss in Michigan?

CBS News correspondent Whit Johnson was joined on Hotsheet Live on Friday by The Washington Post's Glenn Kessler, Politico's Lois Romano, and CBS political director John Dickerson to talk about the GOP race in Michigan.

Rick Santorum and Mitt Romney remain neck and neck in the polls, in spite of Romney's strong ties to the state -- leaving his ability to win Michigan up for debate.

"What we are all about now is Michigan, and I think to an extent Romney's candidacy is on the line," said Romano. "If he loses Michigan, is he going to be able to sustain support from the party? Because that would say he might not be able to win Michigan in the general election."

There may be lingering dissatisfaction with the current field of candidates, but bringing in a new candidate this late in the game would cause complete mayhem for the Republican party, Dickerson argued.

"There are reasons that Jeb Bush, and Chris Christie and Mitch Daniels decided not to run," Dickerson said. "The notion that they would drop into this race late in the process and be able to withstand all the scrutiny, we've seen how difficult it's been for people like Rick Perry," added Dickerson. "The names come up, [and] it is plausible except when you think what would actually happen. It would be chaos."

Also discussed at the Hotsheet roundtable were candidate fumbles at Wednesday night's CNN debate. Kessler fact checked Newt Gingrich's statement about the lack of media coverage of President Obama's votes as a state legislator against "Born Alive" bills, and Romney blaming Santorum for Obamacare.
