In 2000, my friend told me that if everyone who wanted to vote for Nader did so, he would be elected President. I told him that if everyone who wanted to vote for Nader did so, Bush would be elected President. In 2000 a vote for Nader was a vote against Al Gore. Just like in 1992, when a vote for Perot was a vote against George Bush the elder.
Ralph Nader actually spoke at my freshman orientation. "Look to your left, look to your right, one of you won't be here in four years." Most of the freshman weren't in that auditorium for four minutes. There was a stampede for the door.
