1) A small number who are disgusted with the GOP and say this Bob Barr/Ron Paul/Whoever chap is going to get their vote.
2) A small number who are disgusted with the GOP and plan on sitting on their hands this November.
3) A much bigger number who are disgusted with the GOP but say it's a waste of time flirting with Barr or flouncing off in a huff because it's going to be Obama or McCain in the Oval Office so we have to vote for McCain faute de mieux.*
Right now I'm going for door number 2!
