In PA elections are won or lost on the margins. Winning 40% in Washington county rather than 35% could be the difference between winning and losing the state as whole.
LOL, no Democrat is going to take 40% in Washington county even if he comes out with a t-shirt that says I fracking.
Before laughing at me and trying to make me look like a fool, you should educate yourself a bit.
Obama won 42.5% (in 2012) in Washington county, Casey won 47.5% (in 2018), Wolf won 48.5% (in 2018), in 2018 the county gave 42% of its vote to democrats. See there are plenty of examples.
And Neel Kashkari won Orange County by double digits.
