What is drawing more people to embrace the evangelical label on surveys is more likely that evangelicalism has been bound to the Republican Party. Instead of theological affinity for Jesus Christ, millions of Americans are being drawn to the evangelical label because of its association with the G.O.P.
This is happening in two different ways. The first is that many Americans who have begun to embrace the evangelical identity are people who hardly ever attend religious services. For instance, in 2008, just 16 percent of all self-identified evangelicals reported their church attendance as never or seldom. But in 2020, that number jumped to 27 percent. In 2008, about a third of evangelicals who never attended church said they were politically conservative. By 2019, that had risen to about 50 percent.
The second factor bolstering evangelicalism on surveys is that more people are embracing the label who have no attachment to Protestant Christianity. For example, the share of Catholics who also identified as evangelicals (or born again) rose to 15 percent in 2018 from 9 percent in 2008. That same pattern appears with Muslims. In fact, there’s evidence that the share of members of the Church of Jesus Christ of Latter-day Saints, Orthodox Christianity and Hinduism who identify as evangelical is larger today than it was just a decade ago.
