People must beware that the extremely conservative posters on TLS are going to think most universities are too liberal. This isn't true. The perception of what is conservative depends on the individual. In that same vein, bed-wetting liberals think any sort of fiscal responsibility means depriving the poor, and that isn't necessarily true either.
For the most part, people would probably agree that U-Chicago and UVA are the most conservative and Berkeley is clearly the most liberal. After that, the schools fall somewhere in the middle of a continuum between the two extremes. I would put HYS CLS, NYU, and Duke on the conservative side, while I would put Michigan, Northwestern and Cornell on the liberal-moderate side. You can experience a mix of liberalism and conservatism at any T14 law school except for Chicago, UVA and Berkeley.
Also, URM's should not fall into a trap of assuming that only liberal learning environments are healthy for them. I think more of us should study in conservative environments in order to gain healthy, balanced perspectives on the world. Although many here would be shocked, I am a conservative when it comes to many issues. U-Chicago and UVA are great learning environments for URM's, while some of these other so-called liberal schools may not be very good.
