Let me begin with a thought exercise. In 2008, you face a choice between two candidates to vote for. You happen to have a crystal ball that tells you that, if one of the candidates is elected, he will escalate one ongoing war in the Middle East, begin another, step up deportations and extraordinary renditions, attack our social safety net and vastly step up the war on the racial undercaste laughingly referred to as “the War on Drugs.” An unsavory choice, but you can’t vote for the other candidate, because he is a Republican.
