According to Nate Silver:
The good news for Mr. Romney is that while voters often like to defy expectations in the early-going, they usually make fairly rational choices in the end. (Let me be bold enough to suggest that Mr. Gingrich, whose favorability rating is just 27 percent in an average of national surveys, does not ultimately have the stronger side of the electability argument.) Probably not since George McGovern in 1972 have voters nominated a candidate to whom the tag “unelectable” might be fairly applied. And Mr. McGovern’s victory came in part because of his superior understanding of the Democrats’ brand-new nomination system, which he had helped to design.
PPP latest poll still has Gingrich ahead:
Things look good for Newt. He has the lead, his support seems to have more room to grow than Romney's, and so far he's not seeing any ill effects from his ex-wife going to the media. It's important to note though that many average South Carolina voters- the non-political junkies- will get their first exposure to the Marianne Gingrich story in the morning paper or on the news sometime [today]. That may or may not end up having a big impact on his numbers. But it's important to keep in mind.
