To me, Trumps 2020 margin of victory in NC looks roughly the same as 2016.
I think it will higher than 2016 because the momentum is with Trump over the last week and the China Virus drop off of Democrats on Election Day. This year his hard to predict.
I think my 301k number is wrong, I wish I had all my references in front of me but I left them at work. I will see if I can find it again.
My 301k number was correct, at the end of all voting in 2016, 301k more democrats had voted as compared to reps.

I know it is democracy now, but there is good data in the report.
