In fact, it isn't even usually considered a top 20 law school.

I'll admit, that there are probably other law schools just as right wing as University of Chicago.  But I doubt that any of these schools are of the same stature as, say, Stanford, Yale, Harvard, U Va, UC Berkley, NYU, etc.

In this rarified company, University of Chicago is the exception.

My personal experience so far has shown this as well at UVA - of the four major classes I took in my first semester (finally done!), two had Federalist Society members for professors, and the other two were widely known conservatives in other ways.

Not that I'm complaining, having brilliant people who challenge your views is what law school is all about.  Additionally, of the four professors, only one or two I'd be able to pick out as a conservative based solely on their classroom performance.  Partly because it's hard to put an ideological slant on Civil Procedure, and partly because a good conservative professor is the same as a good liberal one - coming out of their class you shouldn't know where they stand.

I am saying, however, that U of C has a reputation, on balance, as being the most right wing of the top law schools in the nation.
