"The contempt that many McCain aides hold for Barack Obama," The Atlantic's Marc Ambinder wrote this summer, "rivals the contempt that McCain held for Mitt Romney a year ago." As Time reported, "McCain and his aides now view Obama with the same level of contempt they once reserved for tobacco-company executives, corrupt lawmakers and George W. Bush. They have convinced themselves that Obama is not honorable, that he does not love his country as much as himself."

The pattern here is perfectly clear. McCain has contempt for anybody who stands between him and the presidency. McCain views himself as the ultimate patriot. He loves his country so much that he cannot let it fall into the hands of an unworthy rival. (They all turn out to be unworthy.) Viewed in this way, doing whatever it takes to win is not an act of selfishness but an act of patriotism. McCain tells lies every day and authorizes lying on his behalf, and he probably knows it. But I would guess -- and, again, guessing is all we can do -- that in his mind he is acting honorably.
