As you say, Daniel, now that he has evidently won the state of Florida, which gives him victories in three of the last four serious contests, John McCain is now the unambiguous frontrunner for the Republican nomination. He is not temperamentally suited to being a frontrunner, as his collapse in the first half of 2007 demonstrated. The best hope for Mitt Romney resides in McCain’s psyche. Can he maintain the self-discipline necessary to stay on point rather than go off half-cocked, say something he shouldn’t, crack a media-friendly joke that will give his enemies on the Right new and more potent ammunition? We’ll see.
