Ralph Nader isn't responsible for GWB.
Joe Lieberman is. He doesn't get the hatred he deserves.
The reason why Bush was not because of Nader, but because many Buchanan voters intended to vote for Gore but the butterfly ballot messed it up, even Buchanan admits it, "When I took one look at that ballot on Election Night... it's very easy for me to see how someone could have voted for me in the belief they voted for Al Gore."
