McCain rose to power on his personality and biography. He was authentic. He spoke truth to power. He told the media they were “jerks” (a sure sign of authenticity, to say nothing of good taste; we are jerks). He was real. He was unconventional. He embraced former anti-war leaders. He brought resolution to the awful missing-POW business. He brought about normalization with Vietnam—his former torturers! Yes, he erred in accepting plane rides and vacations from Charles Keating, but then, having been cleared on technicalities, groveled in apology before the nation. He told me across a lunch table, “The Keating business was much worse than my five and a half years in Hanoi, because I at least walked away from that with my honor.” Your heart went out to the guy. I thought at the time, God, this guy should be president someday.

A year ago, when everyone, including the man I’m about to endorse, was caterwauling to get out of Iraq on the next available flight, John McCain, practically alone, said no, no—bad move. Surge. It seemed a suicidal position to take, an act of political bravery of the kind you don’t see a whole lot of anymore.

But that was—sigh—then. John McCain has changed. He said, famously, apropos the Republican debacle post-1994, “We came to Washington to change it, and Washington changed us.” This campaign has changed John McCain. It has made him inauthentic. A once-first class temperament has become irascible and snarly; his positions change, and lack coherence; he makes unrealistic promises, such as balancing the federal budget “by the end of my first term.” Who, really, believes that? Then there was the self-dramatizing and feckless suspension of his campaign over the financial crisis. His ninth-inning attack ads are mean-spirited and pointless. And finally, not to belabor it, there was the Palin nomination. What on earth can he have been thinking?

All this is genuinely saddening, and for the country is perhaps even tragic, for America ought, really, to be governed by men like John McCain—who have spent their entire lives in its service, even willing to give the last full measure of their devotion to it. If he goes out losing ugly, it will be beyond tragic, graffiti on a marble bust.

Increasingly, there seems to be more and more hostility from the intellectual conservatives against Sarah Palin. If McCain loses, could we see a split between the Evangelical and the Moderate wings of the Republican party?
