The Texas numbers are off. I seriously Doubt that Houston and Dallas have changed that much in a decade--it looks like someone drew random digits on a color-by-numbers. There's a ton of 90% Hispanic precincts next to 90% Black next to 90% White ones, so the numbering system is probably off there, and i seriously doubt University park is now Majority-Black while Western Ft. Worth is Majority WHite.
I'll have to examine. You do get more situations like that in Houston and Dallas (especially Houston) than you might think, but University Park ain't black, of course.
Anyway, I'll get back to work now.
