Good point. You might actually see Repubs and Democrats work together though, if only to stonewall anything the 3d party guy tries to do.
Except for the Libertarians, Reforms, and US Taxpayers party. They're either right wing nuts, or just plain out bat-s*** crazy.
Oh yeah, I voted for Nader in 2000. Voted in Indiana - when you know Bush is going to get 65 - 70% there you dont have to vote against who you dont like, you can vote your conscience.
