UNC took a dive this year in the rankings, but you can see that it's short-term by just looking at their peer and lawyer/judge reputation scores on USNWR. UNC is definitely much more national (though calling them national would not be right either [not that that's what JD was saying]) than GMU.
But on the flip side, the new Dean knows that there is a problem with state funding. Moreover, there is a new chancellor starting in a few months, who will hopefully realize the importance of the state having a premier state law school. And finally, a 200,000 square foot law building is expected to open fiscal year 2010-2011 at Carolina North; it's being paid for with state funds. http://media.collegepublisher.com/media/paper885/documents/q9t31r37.pdfAnd I've been to the Arlington campus. Not 5 minutes after getting there did I decide I wouldn't apply. I disliked the location that much, even while being near DC. It should also be noted that the peer assessment of GMU is the 2nd worst in the USNWR top 50. UNC is in the top 20. The quality of students at GMU is also not obviously better. Their 25th/75ths are 160/166 and 3.1/3.8. UNC's is 158/164 and 3.4/3.8. To keep things in perspective, UNC's class size is significantly (almost 40%) larger.Not trying to troll here, but making sure that it's clear to the OP that things aren't just as you say.
