The performances wrap the narrative of election fraud in a megachurch atmosphere, complete with worship music and prayer, and have drawn criticism from some Christian clergy. When the tour came to a church in San Marcos, Calif., this month, a local Methodist minister denounced it as an “irreligious abomination” in an opinion essay.

Smaller churches, meanwhile, have proven an important support network for the individual activists who now travel the country promoting the narrative of a stolen election.

“Churches and bars, baby. That’s where it was happening in 1776,” wrote Douglas Frank, a high school math and science teacher in Ohio whose widely debunked analyses of the 2020 results have been influential with election conspiracists, in a Telegram post last month. So far this year, more than a third of the speeches he has promoted on his social media accounts have been hosted by churches or religious groups.
