Trump's success with working class voters

 NBC News - Over the last 20 years, the counties where Republicans have improved their presidential vote share by the largest margins are predominately centered in Appalachia and the surrounding areas. The 100 counties that saw the largest shifts include: 11 of West Virginia’s 55 counties, 27 of Tennessee’s 95 counties, 18 of Arkansas’ 75 counties and 17 of Kentucky’s 120 counties.

These counties, on the whole, are much more heavily white than average, according to census data, with white residents making up at least 90% of the total population in about two-thirds of these counties. All but 12 of those counties are at least 75% white. The unemployment rate across these counties is about twice the national average. Residents are more likely to be reliant on food stamps and less likely to have moved in the last year. Residents of these counties, on average, also are significantly less likely to have a bachelor’s degree or higher.

While the national average in the American Community Survey’s most recent five-year estimate is that 35% of Americans have a bachelor’s degree or higher, the average in these counties is just 14%.

In short, the shifts show how Trump has brought more white working-class voters into the GOP, causing spectacular changes in some localities.
