Some of this information is inaccurate. Wisconsin has produced 1 SCOTUS clerk (Cecilia Klingle) that I have found. If you know of more, please post their names.
In Milwaukee, Marquette and Wisconsin ARE considered in the same league by many. This is because there are literally thousands of Marquette alumni in the area, and many are in positions of power. It is strange, but those who went to Marquette still hold their grads in high regard, though Wisconsin is much more competitive. As for your contention that "a very large" portion of students here are interested in Public Interest (PI is NOT used as an acronym for public interest in the legal field, it is usually reserved for Personal Injury lawyers by the way): while many wanna be law students list that they want to do pubic interest law on their applications, most don't go into it after graduation, or even pursue this part of the profession much in law school. NALP and LSAC both have good statistics on this.
I've been stalking this thread for awhile, and as a UW undergrad and probable (barring a miracle) law student I thought I'd jump in here. I'm from Milwaukee and many lay people in the area definitely consider Marquette and UW as peer schools (unjustifiably so IMHO). But I know for a fact that big firms in Milwaukee will recruit deeper into the class than at Marquette. Legal professionals know that UW is the better school, but Marquette alumni still hold their graduates in high regard. I guess I didn't really add anything new to this discussion, just a vent because I constantly get asked "Oh, did you apply to Marquette too?" And I've gotten sick of trying to tactfully say that I wouldn't go there even if they gave me a full ride. Just my .02
That being said, if you are coming to UW you should be very excited. It's a great place to go to school and a great place to live. I've already lived there for four years and am excited about coming back for another three. I know there are a couple of other UW undergrads here but if there are any more questions I'll jump in with any answers that I can give.
Get your football tickets ASAP, game days are ridiculous. *uck'em Bucky!
