I will absolutely NOT vote for any Republican or Democrat besides Paul. Any such vote would be a vote against the Constitution, and I will never vote against the Constitution again.
Enough of this "lesser of two evils" business. I fell for that when I voted for Bush in his first term in order to keep Al Gore out of office. You see, back then I didn't know the difference between a REAL conservative and a NEO-conservative. The neocons have completely hijacked the GOP. The Democrats, of course, are the same as always.
How many here would vote for a Communist or a Nazi if those were the only two candidates who had a realistic chance of winning?
The most important issue in any election for me is gun rights, since you have NO rights whatsoever if you don't have the means to physically defend them by force. Make no mistake, Giuliani and Romney are anti-gun -- they would sign the same legislation that Clinton or Obama would sign. McCain says he's pro-gun, but that might mean he "supports hunting and target shooting." Anyone who doesn't believe Americans have the right to own military-grade firearms for the purpose of protecting their liberty against their own government (not against "blue helmets") is an anti-gun, anti-Constitution, and anti-freedom SOB. Ron Paul understands this (see my sig line). What other candidate does?
If Paul doesn't get the GOP nomination, then I hope he runs as an independent, in which case I will vote for him anyway. If he doesn't run at all, then I'll vote Libertarian, since Libertarians are always pro-gun and pro-Constitution (though I don't always agree with them 100% on some issues, like immigration).
