In the 2020 election, 27% of voters identified as either “white evangelical” or a “white born-again Christian.”
According to Edison Research, 76% of them voted for Trump and 24% voted for Biden. This means that Biden received four million more white evangelical votes than Hillary Clinton received in 2020. (Biden is currently leading Trump by more than 6 million votes nationwide).
Here is some exit polling. If these exit polls are correct, it appears that the white evangelical vote helped Biden in Michigan and Georgia. (We don’t have polling for the evangelical vote in Arizona, Nevada, Pennsylvania, or Wisconsin).
In Ohio, Biden won 18% of the white evangelical vote. In 2016, Clinton won 20% of that vote.
