"In fact, if he had supported Gore, the election wouldn’t have even been close." 

Have to disagree with you on that Hugh. We had good reasons for not voting for Gore. Before he discovered global warming, which I'll give him a lot of credit for, Gore was another Bill Clinton, a conservative pro-business southern Democrat hawk, only without Clinton's political skill. During Clinton's first term Gore wanted to reduce Social Security benefits. He had to be told that the typical SS recipient was an old woman who barely made ends meet. 

He was a lousy candidate who didn't even carry his home state of Tennessee. Nader was not to blame for Gore's defeat, which was deserved. A lot of us were sick to death of the Clinton presidency by 2000, and we were not going to vote for its continuation by Gore. Nor will we vote for a repeat by Hillary Clinton. We are revolting against business as usual, as we did in 2000. The Democratic party can move left or die.
