I agree. As noted below, one option for McCain is to focus on the "racial resistance among white voters" but that sounds too much like playing the race card. If McCain does that he would probably lose the election and his honor. So how can he fire the campaign and win.
He should give a speech that acknowledges that some have suggested that he focus on the "racial resistance among white voters." He could then categorically renounce the suggestion and instead say that henceforth he will campaign as serious but cheerful candidate. Further, because the country is so deeply partisanly divided, McCain should announce that if elected that he would ask Palin to step aside so that he (McCain) could nominate Obama as VP.
Another brilliant NBB solution, don't you think.
P.S. Yes, I realize that he might alienate some rabid Republi-cons, but I think McCain would rather lose with honor than win by focusing on the "racial resistance among white voters," which in my opinion would be dishonorable. If you think there is another way McCain can win, let's hear it.
UPDATE: An alternative strategy would be to focus solely on the 'split government is better government' argument. That is, government works better when one party doesn't control both the executive and legislative branches. In any case, McCain needs to do something.
Others are making suggestions. See Washington Post, What Could Change the Election? The Post asked John Podesta, Newt Gingrich, Mary Beth Cahill, Peter J. Wallison and Stuart E. Eizenstat what would be an election game-changer.
