Here is the county color map between Hillary! and Trump in 2016. Pa-thetic, on the Socialist Democrats part. Don't forget that Gary Johnson and Jill Stein snagged about 200,000 votes from both parties in PA in 2016, too. No Libertarians that I know are all that excited about Libertarian Jo Jorgenson and Howie (WHO?) Hawkins is running for the Green Party. I don't see these two taking as many votes in PA as in 2016.
Also, how many voters who were wary of voting for a New York billionaire, but have now seen his accomplishments will show up this time?
