Just to clarify for you guys, some schools do actually have majors in pre-law. Though you'd be a fool to do it. Most schools just have a pre-law advising program. Certainly no reason not be involved in that, in my opinion.
As far as what majors are best, I think there is no right answer except to say that you want something challenging. Whatever your major, schools just want to see that you challenged yourself and that you worked hard. And I love when folks say that philosophy majors to well on the LSAT because that makes me confident! Personally, I am a double major in Philosophy and Political Science. I hate poli sci, but I've heard from adcoms that this is a fantastic combination. Plus double majoring makes your whole college experience just a little tougher, which they always like.
