Baylor is probably offering the most attractive site, but it may still be too Baptist for selection. (Yes, I know they hired a Presbyterian to run it, but he's indicated that he is going to convert back to Baptist.) The recent troubles in the basketball program won't help, either.
I would be surprised if either of the other two were chosen. Tech is just too far from anywhere, and I don't know of any links to UD that the Bush family has. (Jeb's family is a Catholic, but I can't see that being a factor.)
I heard SMU bought the old Mrs. Baird's bread site. I think it's probably a two way contest between SMU and Baylor. Doubt the Baylor men's basketball problems will have any bearing on the decision. Besides, the women's basketball program produced last year's NCAA champs : )
