It seems that many white Evangelical voters are more concerned with being on the right side of an issue than to really analyze the situation and to make a righteous decision.
The AP VoteCast survey shows that 81% of White evangelical Protestant voters went for Trump this year, compared with 18% who voted for Biden. The Edison exit polls estimate that 76% of White evangelicals voted for Trump, 24% for Biden.

A notable fact in 2016 was that exit polls showed about 80% of white evangelical Christians supported Trump in spite of his unfamiliarity with the Bible, his divorces, his vulgar rhetoric and his association with porn stars. Trump’s reputation in moral terms hasn’t changed all that much during his time in office, but there is little evidence of slippage among these faith voters.
Surveys of early voters and exit polls this year showed between 76 and 81% of white evangelical and “born again” voters supporting Trump, according to the National Election Pool and AP/Votecast.
