I think the key is to vote third (alternative?) party in smaller elections (mayor, state senate), and then work up.

Voting third party for congress is mostly a waste of time for now, and it doesn't seem likely that we're going to see a massive enough shift in voter participation to change that all in one go, but I think with enough effort to build up non-D/R party support at the local level that could change a lot faster than most people think.

I'm less optimistic about the presidency, really. I doubt the reigning parties will let that slip out of their hands.
