What counties will Rubio win?

[ElectionsGuy]

This is actually pretty easy since Rubio's best demographics thus far have been urban, higher income, higher education, suburban Republicans. Here's the counties I think he has a shot to win...

Alabama: Jefferson and Shelby (coincidence that it includes the first and last names of the Senators)
Alaska: No idea
Arkansas: Saline, Faulkner, Benton
Georgia: Fulton, DeKalb, has some shot at Cobb and Gwinnett
Massachusetts: Middlesex?
Minnesota: The ring: Washington, Dakota, Anoka, Scott, etc.
Oklahoma: Seems like Cruz would steal votes away from Rubio here, but if anything the two big ones.
Tennessee: Williamson, Davidson, Sumner, etc.
Texas: None (since Cruz will win with the generalized Rubio demographic here)
Vermont: Don't know
Virginia: All of Northern Virginia, Virginia Beach, Chesterfield and Henrico

[100% pro-life no matter what]

I would add Shelby, Rutherford, and Knox for Rubio in Tennessee

There's no way you're going to tell which "counties" Rubio wins in Alaska.  Results will only be broken down by House District.  Some of them span multiple Alaska County equivalents (though we probably can easily tell who wins Anchorage, Juneau, Kenai Peninsula Borough, and, if it's not close, Mat-Su Borough).

Rubio's best shot in Alaska is probably in the Southeast (Juneau, Ketchikan, Sitka, etc.), which is more liberal than the rest.  Anchorage will probably vote like the rest of the state.  The conservative Kenai and Mat-Su areas could be Trump's best area.  Especially Mat-Su, since Palin is from there and it is fairly downscale/exurban.

Based on previous exit polls on Trump dominating with veterans, he will win Virginia Beach.
