Thanks for the county vote link.
With the below one from the 2016 election, you can see county by county where the 2016 GOP voters did not turn out.

Of course, given the small % vote difference, and the demographics of the state, I think all it took for Jones was to concentrate on the major population counties like Montgomery and Jefferson and that was enough to eke out the small margin of victory; also “get out the vote” is usually easier to work out in the major cities. Yes I know, even then, if not for that, it would have meant a strange victory for Moore, with so many 2016 Trump voters not voting.
