Splitting up the Conservative vote is a good way to elect Democrats.
Yep. It'll be a feel-good protest vote that's wasted. That's why Lefties won't vote for Nader and that's why we shouldn't vote for Peroutka. They are never going to win and its being in power that determines how far you can advance your beliefs.
I wouldn't necessarily take Libertarians over the Constitution Party. The goal is to elect one or two candidates, not reduce Republican seats.
