Obama-Obama-Trump counties that trended D in 2012

I'll attempt a non-snarky response to this well-researched question (though I can't figure out the rationale behind the ordering of the counties).

The only region conspicuously absent is the West (Pacific as well as Mountain).

I'm going to guess: (1) Obama's Hurricane Sandy bounce; (2) Trump's resonating with residents of New York State (but not NYC itself, except for Staten Island); (3) an abundance of Sanders primary supporters who voted 3rd party in the GE-- particularly those who voted Obama in 2012 and were too young to vote in '08.

Well done!

So the question now, fellas, becomes which of these counties remain TRUMP counties in 2020?

And in case anybody was wondering, there were six McCain - Romney - Clinton counties -- one of which was my homebase Fort Bend County.  

I'd say most such counties that went for Trump by less than 2% (in the Northeast) or 3% (in the Midwest) will flip. In the South, I predict Martin, NC will flip.
