Since the 1970s, white evangelicals have formed the backbone of the Republican base. But as younger members reject the vitriolic partisanship of the Trump era and leave the church, that base is getting smaller and older. The numbers are stark: Twenty years ago, just 46 percent of white evangelical Protestants were older than 50; now, 62 percent are above 50. The median age of white evangelicals is 55. Only 10 percent of Americans under 30 identify as white evangelicals. The exodus of youth is so swift that demographers now predict that evangelicals will likely cease being a major political force in presidential elections by 2024.
And the cracks are already showing.
