Richard Cohen (self-admittedly previously "in the tank" for McCain) succinctly and devastatingly lays out his utter disappointment in The Ugly New McCain. It sums up my previous and current feelings on him as a person and a candidate. The most damning parts of the article, IMHO?
"McCain has soiled all that. His opportunistic and irresponsible choice of Sarah Palin as his political heir -- the person in whose hands he would leave the country -- is a form of personal treason, a betrayal of all he once stood for. Palin, no matter what her other attributes, is shockingly unprepared to become president. McCain knows that. He means to win, which is all right; he means to win at all costs, which is not...And so McCain lied about his lying and maybe thinks that if he wins the election, he can -- as he did in South Carolina -- renounce who he was and what he did and resume his old persona. It won't work. Karl Marx got one thing right -- what he said about history repeating itself. Once is tragedy, a second time is farce. John McCain is both."
