A horrible, self-inflicted blow to McCain's credibility.

Something that I never imagined possible has just transpired, and a man for whom I had a lot of respect has just lost much of it. It appears that for some reason John McCain, one of Washington's most stalwart and unwavering critics of torture who was himself tortured in Vietnam, has voted against a bill that would ban the practice:

I simply cannot see any explanation for this except politics - that McCain feels the need to appease the Republican far right at this point in time, and, tragically, the right to torture has now become a litmus test of "conservative" orthodoxy. It's a Karl Rove wedge issue of a classic kind: using the crudest of emotional appeals to gin up populist authoritarianism for the sake of Republican partisan advantage in wartime. There is nothing conservative about torture, of course. But the authoritarians of the far right are hardly conservatives in the traditional sense either.

So McCain reveals himself as a positioner even on the subject on which he has gained a reputation for unimpeachable integrity. It's worth reading Jon Chait's illuminating new piece in this context. I repeat that I am heartbroken. McCain has indeed been a leader in preventing the military from torturing terror suspects, and in banning waterboarding. But by leaving this lacuna in the law, he gives this president the space he wants. As president himself, of course, McCain would surely instruct the CIA to uphold the American way of interrogation, and not to adopt techniques once used by the Gestapo and prosecuted by the US as war crimes. But we now know that there will be one difference between Obama and McCain in November. One will never tolerate torture; the other just did.
