2016 White and Non-White Vote by County Project

[100% pro-life no matter what]

Good work!  Some seem hard to believe, like the county in Alabama where Trump apparently won the non-white vote.  Obviously, assumptions have to be made, which can skew things and produce a couple weird results.  I'm surprised that you have Clinton winning the Davidson County (TN) white vote.  I figured Trump probably narrowly carried it, but it may be in your margin of error anyway.

Statewide using your numbers for the white vote:

Trump's best states with the white vote:
1. Mississippi: 89%
2. Louisiana: 84%
3. Alabama: 83%
4. South Carolina: 75%
5. Georgia: 75%
6. Texas: 74%
7. Oklahoma: 73%
8. Tennessee: 72%
9. Wyoming: 72%
10. Arkansas: 71%

Clinton's best states with the white vote:
(DC: 86%- Mississippi whites were actually more unified than DC whites)
T1. Massachusetts: 56%
T1. Vermont: 56%
3. Hawaii: 52%
4. Rhode Island: 50%
5. Washington: 48%
T6. Connecticut: 47%
T6. Oregon: 47%
8. Maine: 47%
T9. California: 47% (narrowly won)
T9. New York: 47% (narrowly lost)

Now, in some cases, these are different from the exit polls, but, usually, they aren't too far off.

Whites in Knox County (Knoxville) (29.7%) and Hamilton County (Chattanooga) (27.4%) voted more in favor of Clinton than Whites in Shelby County (Memphis) (26.7%). It's not by much in Chattanooga, but Knoxville Whites voted a full three percentage points more for Clinton than Whites in Memphis and its suburbs. I suppose the racial tensions in Memphis have something to do with the discrepancy.  

UT-Knoxville, which is the flagship, is located there. Knoxville, as far as I know, isn't much of a college town culturally in the vein of Austin or Madison, but it's probably enough to make up a good bit of that difference.

Whites in Sarasota County, FL (39.2%) voted more in favor of Clinton than Whites in Hillsborough County (37.8%). White's aren't exactly a liberal bunch along the Western coast of Florida, but I'm surprised that any county along the retiree-laden southwest coast managed to have its White population vote to the left of the Whites in the county where the Tampa Bay metro anchor is located, if for no other reason than out of consideration to the general rule of thumb that Whites in larger metros are more Democratic than Whites in nearby smaller metros unless there's a really obvious reason to the contrary (college towns, ski resorts, bohemian lifestyle communities, etc.).

I've been to Sarasota before. The impression I got was that there's a certain moneyed "bohemian" culture to some of the city which presumably increases the white vote Clinton vote somewhat. There's also a small liberal arts college, The New College of Florida, by the county line in Manatee, which probably has a slight effect.

There's also a non-negligible Amish population if that makes any difference, though it probably doesn't.

That school is neck-and-neck with Oberlin for the most liberal (culturally) school in the country, so it might matter more than the average small college.
