No, I would not. As others have said, a vote for any GOP candidate other than Paul is a vote for four more years of Bush. It's also a vote against the Constitution, and a vote for more pointless wars overseas.
I don't think this country will survive if the neocons stay in power for too long -- and frankly, if Americans keep them in power, then it doesn't deserve to survive. Not only will we see the last of our liberties and privacy go down the drain, with illegal wiretapping and general police-state surveillance, but America will also go bankrupt. What's the national debt now? Something around 10 trillion dollars and rising?!
Of the GOP candidates besides Paul, the one I dislike the least is Huckabee. But he's still a neocon who stands for big government at home, military intervention overseas, and generally telling the rabble in the sports bars what they want to hear.
If a Democrat gets elected, then unconstitutional anti-gun legislation may be more likely to pass. If gun owners comply with it, then they don't deserve to have those freedoms anyway. Only brave people can be free.
