Lieberman is right on the WOT, but I’m not sure how ‘principled’ he is; he did run with Gore in 2000.
Joe Lieberman is a die-hard leftist, but he has been rock-solid in his support of the war on terror and he risked his political future to support it. That actually makes him more principled that Roody, because Roody has never thought of anyone but himself and his future.
