The Reasons Christopher Buckley, the son of late Willliam F Buckley, no longer endorses McCain

He writes:

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?

I have a hard time disagreeing with this sentiment.
