Ok, flashback

Yglesias, in a widely and correctly praised post from almost exactly four years ago:
Christopher Hitchens, in one of the few insightful things he's said about the war on terrorism, took the chance in his final Nation column to criticize those on the left "who truly believe that John Ashcroft is a greater menace than Osama bin Laden." At the time, I thought it was a very sharp remark. I never supported Bush and always hoped he would lose in 2004 since I thought his policies were misguided, but many people seemed to me at the time to have lost all sense of perspective about who the really threatening enemies were. Suskind's article along with other pieces of evidence of what one might call the creeping Putinization of American life (the Sinclair incident, the threatening letter to Rock The Vote, the specter of the top official in the House of Representatives making totally baseless charges of criminal conduct against a major financier of the political opposition [shades of Mikhail Khodorovsky], the increasing evidence that the 'terror alert' system is nothing more than a political prop, the 'torture memo' asserting that the president is above the law, the imposition of rigid discipline on the congress, the abuse of the conference committee procedure, the ability of the administration to lie to congress without penalty, the exclusion of non-supporters from Bush's public appearances, etc.) are beginning to make me think this assessment may have been misguided. Terrorist forces operating in and around Chechnya have done some horrible things -- I was in Moscow for the big apartment bombings -- but ultimately the most harmful thing they have done was to enable Putin to tighten his grip on power.
That was four years ago, and was frightening at the time, but since then those trends have worsened. It's time for a change.

While one might argue those are policies of the Bush Administration and so anyone winning this election will constitute a change, they're all endorsed from by the Republican party, both at its top-levels and at its base. Without repudiating the Republicans, and not just Bush, there is no chance of reversing direction. John McCain is a Republican.
