Lieberman may support the war, but he still tried to deny the warriors their right to vote.
That explains the smattering of golf claps.
Russert asked Joe about counting the military ballots that the Gore people said were technically flawed (and which, if counted, would easily sink Gore's chances). Lieberman said, "I would give the benefit of the doubt to military ballots." And "Al and I would not want to be part of anything that would put an extra burden on the military personnel abroad who want to vote."
This caused extreme dismay in the Gore camp.
