At this point, Lieberman seems primarily motivated by torturing liberals. That is to say, he seems willing to cause the deaths of hundreds of thousands of people in order to settle an old electoral score.
Well, in fairness to Klein, political history does make it tough to tar Lieberman as a racist, illiterate, tea-bagging militiaman, but settling old electoral scores is pretty fey stuff considering the recent expansive liberal palette. Don’t get me wrong. I like the he wants to murder hundreds of thousands of people, I just think the motivation needs to be sexed up a bit. Maybe Lieberman is a closet Nazi? It can be done! Remember The Believer?
