I don't want to discourage anyone from voting L, but have you looked at the Constitution Party? If I recall correctly, it pretty much mirrors the LP position of calling for drastic reduction in size of gov't while advocating a lot of conservative social views (blue laws, WOD, state-sponsored religious activities, etc).
Personally, I have a problem with the LP position on open borders & "free trade", but there's no way I could vote republicrat for the reasons you mentioned. The reason we've veered so far left as a nation is because most people vote for what they perceive as the lesser of two evils.
Vote for the people who most represent your views and values... if you do that, you exercised your right to vote in the way the founders of this nation intended us to, no matter what the "bushies" say
Its best to make your vote count, why else be into politics?
