Since I usually identify myself as a libertarian, everyone's been saying I should vote for Ron Paul. It's unlikely. My biggest concerns with him are:
1. Against gay marriage and adoption, and in favor of "don't ask, don't tell. Admittedly with a Democratic Congress he wouldn't be able to do a lot of damage. But he could block legislation that could secure rights for homosexuals, even if it doesn't involve federal money. He wouldn't try to ban gay marriage at a federal level, but at the same time he wouldn't allow laws that would prevent states from invading people's private lives. I know it won't happen for a long time, but we really need a constitutional amendment saying that the government cannot discriminate on the basis of sexual orientation, same as we needed one that said they couldn't do it on the basis of race (There's not enough discrimination against women any more to warrant making that an amendment).
2. No federal money for schools. The one way in which I am really, truly not libertarian is that I think that we need to provide for children and the mentally handicapped or ill. But again, it's unlikely he would be able as president to decimate the federal school funding system, and on top of that at least he would push to repeal No Child Left Behind.
3. Anti-abortion. But he's agreed to leave the question of abortion to the states, which is something. With a Democratic Congress, which we will most likely have, that wouldn't be too disastrous.
4. He opposes the UN.
However, I agree with his fiscal and international policy ideas, and the concepts of state's rights and minimal intervention at the federal level. I've always felt that the only thing the federal government should enforce on the states are basic human rights and equality, and if necessary, protections for minors and the mentally handicapped/ill. Ideally the states would take care of the minors and mentally ill themselves, but they don't.
But I most likely won't vote for Ron Paul because of his stance on the rights of homosexuals, and I wouldn't vote for him anyway unless it looked like my vote didn't really matter in terms of keeping the religious right out of office.
