Voting and vote counting has been on Auto-Pilot since 1960.
The county is blue because there are 21k Ohio University students voting there and a couple of thousand more faculty. Take that out of the equation and it is as conservative as the rest of non-urban Ohio. You want to find poor or working class people in Ohio who are still Democrats you have to go to someplace like Youngstown and even that is changing. Pretty soon the Dem party is going to be reduced to a few dots between the two costs, mostly college towns and some urban outhouses like Chicago and St Louis.
