Dear John McCain:

You were right on Iraq when others were panicking or saying nothing. Your national-security experience, aversion to pork-barrel spending, recognition of global warming as a problem, and refusal to get too close to the religious right, are all major points in your favor. Yes, you have some big-government tendencies I dislike, and your campaign-finance “reforms” were wrongheaded. Overall, you are the most attractive candidate. I will vote for you on Super Tuesday, and hope to do so also in the general election. But if you do something crazy—like select Huckabee as your running mate—all bets are off.
