Very good reply! That was one of the oddest spectacles I have witnessed on the floor of the Senate -- made no sense. He acted like his best friend had been killed. If he gets choked up and cries about the nomination of the UN Ambassador, then it is time for him to resign. Voinivich looked on the verge of a nervous breakdown -- really strange since as you said he didn't even bother to attend most of the hearings on Bolton.
But something is clearly amiss IMHO and I agree that he should consider getting out of the Senate.
