Setting aside blue states with moderate Republican governors, I see: 1/10 (Duke) 5/20 (Duke, Notre Dame, Vanderbilt, Rice, Wash U) 15/45 (Duke, Notre Dame, Vanderbilt, Rice, Wash U, Emory, Ann Arbor, Wake Forest, UVa, Georgia Tech, UNC-CH, UF, Case Western, College of William and Mary, Tulane)

I doubt the split would be at the top 10 because they're simply too small to absorb all the domestic demand. I'm not sure how far down the list, however, would be the switch point between benefit and harm (or if it would be determined purely by rankings vs. some other consideration).
