Reply #137: That evidence is in the polls taken after Gore picked him.

[drummo]

He got a 5% jump. Where do you think those voters came from?
Liberal circles?
If after picking Lieberman his poll numbers had gone down you would be right. But the opposite happened.

As for liberals and progressives who went to Nader, I don't blame Joe, who I don't like very much by the way. I blame those stupid liberals and progressives, including Michael Moore, who believed there was no difference between Gore and Bush.
I blamed those idiots at "Enviromentalists against Gore" who claimed that a Bush presidency would be actually better for the environment than Gore.

To have any chance to win in 2000 Gore had to separate himself from Clinton's immorality and lies. (Yes whether you believe it or not there were millions of voters who cared about such things even if you didn't)Picking Lieberman helped him to do that and there is no evidence that he lost more votes than he won because of that decisions. Nor is there evidence that he would have won more votes with someone else as his running mate. All that is just mere speculation.
