The big news we're covering, of course, is the result of the South Carolina primary. But there's also some big news out of Florida. The state's very popular Republican Governor, Charlie Crist, has endorsed John McCain. Normally endorsements don't mean much. And this one may not either. But McCain and Romney, as I noted earlier, could scarcely be closer in the polls right now. So on top of the endorsement of Sen. Martinez (R-FL), which came yesterday yesterday, this could be significant.
