Well, there really isn't such a thing as a "pre-law" major. There are some majors, like philosophy or political science, that are fairly popular among students who end up deciding to go to law school, but in reality, you can major in anything and still go to law school. Unlike pre-med, there isn't really a set of courses you're required to take in order to be eligible to go to law school. Of course, there are various student organizations that are geared towards students who are looking to go to law school, but as far as majors/classes are concerned, you just need to make sure you take courses that help you develop your reading/writing/critical & analytical thinking skills.
As far as actually getting into law school is concerned, your actual undergraduate school really isn't all that important. The two major things law schools consider when looking at an applicant is LSAT score/undergraduate GPA. In that respect, a candidate who doesn't go to an Ivy League school for undergrad but has a stellar GPA would generally be more preferable to a law school admissions staff than a Yale graduate who only got a 2.5.
It's really important to not base your choice for undergrad on where you assume will make it easier to get into law school, because the influence of your undergraduate school is really limited. Tour a variety of colleges and find out where you think you'll feel comfortable as a student. Then, once you're there, work hard to get a great GPA, get an internship at a law firm, or at least talk to a wide variety of lawyers to get a feel for if being a lawyer is actually for you. I'm in the pre-law organization at my university, and there's a considerable number of active members who have no interest in going to law school, even though that was the only thing they saw themselves doing as freshmen.
