This group of voters could swing the 2020 election

Few questions may shape the result of the 2020 election more than whether Democrats can exploit the religious gap in attitudes toward President Donald Trump that has emerged among his core constituency of working-class white voters.

While polls generally show Trump retaining strong support overall among blue-collar whites, more detailed results in several recent surveys reveal a critical distinction: Trump faces much more resistance among working-class whites who are not evangelical Christians than among those who are. If Democrats can advance through that opening, it could prove crucial in 2020, because evangelicals compose a much smaller share of the white working-class population in the pivotal Rust Belt battleground states, such as Michigan and Wisconsin, than they do in the South.
