Buchanan didn't run to elect a Democrat. Besides, Bush is a Liberal in a Republican's clothing.
The Green Party took more votes away from Gore than Buchanan took from Bush.
As I have stated in previous comments, the current system is part of the reason why third parties aren't being elected. I would, however, like a Republican like Buchanan to run for President.
Pat Buchanan is a lightning rod that brings out the Democrat vote. He is a proven loser who lets his opponents define him with no effective response on his part. His message doesn't translate to votes, so either he is the problem or his message is the problem or both are the problem.
