Please name said "viable" third party, and candidates would be even better, for November. Sorry, but as bad as you think the GOP are on this issue, you already have people like Tancredo and Sensenbrenner (sp?) in the House - you really want to turn them out too?
Well, I pulled my head up out of the sand a long time ago and quit worrying about individual Congress critters in any party (even though there are still a small handful worthy of some consideration on certain issues from time to time). I've since become result oriented and I see none coming from neither the Dimocrat's nor the Republicrat's so I'm looking outside the two failed parties to date for some possible answers. As long as (fiscal-)conservatives keep making feeble excuses for the failed Republican Party and their ever leftist driven ideology and agenda then things will never change. Like more and more (core or social-)conservatives today I've finally had a belly full of the liberal wing of the Republican party. It took me the better part of 33 years to finally see just how liberal as well as morally corrupt / bankrupt and out of touch my old party has become with me, one of their original core conservative constituents.
It's time to change horses in this race. My old one is giving out.
