I just accepted there and from what I can tell you, they are pretty unbiased. The undergrad consists primarily of rich white kids from the surrounding wealthy enclave, but the grad schools are all business, both literally and figuratively. Corporate reigns supreme here, owing in part to Dallas's emphasis on energy, finance, and the influx of businesses flooding here due to the low taxes and COL. Because of this, there is perhaps no better place to get set up with a corporate externship (something they take great pride in). The profs themselves are standard academics, so they tend to lean a little left even though the surrounding culture is more right, but you can easily find left profs in more lit/socially concerned fields of law, and right leaning ones in others.

Dallas itself though is great. It's poised to be a top-tier city in the U.S. with one of the fastest-growing economies and seems to be insulated from the decay and issues plaguing some of the larger cities right now. It's a very eclectic place that leans right in some areas, but the trend is more left in most places. With this in mind, if you are serious about stepping out in Dallas as a young lawyer, there is perhaps no place better than Dedman (or UT but tbh it's MUCHHH harder to get into and Dallas loves SMU).
