Conservative scion Christopher Buckley thinks that John McCain has sold his soul, and gotten little in return.
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? (source)
