White evangelicals have been among Trump’s strongest supporters. About 80% of them voted for Trump in 2016, a figure that more or less held steady in 2020.

One of the more interesting demographic groups is also among the fastest growing: Americans who say they have no particular religion. These “nones” broke heavily for Biden, with 72% voting for the former vice president.

Nearly 80% of registered Republicans are Christian. For Democrats, that number is 52%. Democrats are much more likely to be religiously unaffiliated.
