In the long-term, I’m inclined to agree that (especially if Obama’s presidency is generally regarded as successful) McCain’s disgraceful campaign will be seen as the last gasp of Nixon’s Southern Strategy as a successful tool for the GOP. (I also think that it would eventually come to be seen that way even if he won, especially if he proved to be an unpopular one-termer.) In the short-term, though, I’m not sure. Given that even writers appalled by McCain seem to see his behavior as some sort of betrayal of McCain’s fundamental nature, my guess is that most of them will forgive him just as they’ve done so many times before. McCain will apologize, claim that Obama made him do it, serve some BBQ, and journalists will start swooning again.
