You probably remember the 1960 election when religion was definitely a factor. John Kennedy, the first Catholic to run as president fought off allegations that he would have to consult with the Vatican before making important decisions. "https://www.voanews.com/usa/biden-places-his-catholic-faith-front-and-center" In this article, Biden is described as anti-abortion and a devout Catholic." As a senator, he voted repeatedly to uphold a ban on federal funding for abortions. But as president, he said the ban should be lifted." The Catholic Church claims 22% of the US population as registered Catholics.
James you make sound arguments about the "nones". My personal view is that Biden won the never Trump vote.
