Trump won my precinct, I'm shocked to be totally honest with you but if any republican could've won it would've been Trump. My precinct is a mix of very upper class $150,000+ and a large working middle class with many plumbers, electricians, welders etc. It is also heavily white.
My precinct is exactly like this- 45% Irish and >90% white, lots of nice houses, lots of plumbers and the like; but Hillary won it although not as solidly as most of the other precincts in my town. Trump will easily win here in 2020 if he does a solid job, though.
