Of course you can’t predict voter turnout, but I think that it would increase. I’m only guessing, but I don’t think its a crazy prediction.
As for the map, that is totally my fault. I failed to notice that it’s a.change from 2012. But I think my point still stands. Take Minnesota and New York again. All those counties saw a new influx of voters for Trump except TC and NY and those states still went blue. It shows the big cities still have a huge sway over the rest of the counties.
