Actually, this is a little bit of leftist revisionist history trying to blame Lieberman for the 2000 loss, started by the nyt.
Lieberman was trying to shield the dems from Republican accusations that they were trying to throw out military absentee votes. He did not, in any way that I am aware of, attempt to change the dem strategy of fighting to have the absentee military votes discounted.

According to Bill Sammon’s book “At Any Cost” his take was also that Lieberman wouldn’t go along with the Gore plan to spike the military ballots. You saw the clip yourself, didn’t you? He said what he said. I guess we could always be suspicious of him and never attribute good intentions to him, but I don’t see the purpose of that. Do you?
