He grew up on a farm in Indiana, the son of a factory worker and eldest of five children. He studied at Liberty, a Christian university founded by the conservative pastor and televangelist Jerry Falwell, and recalls wearing a T-shirt expressing opposition to Democratic presidential candidate John Kerry.

Two decades later, Justin Douglas is running for the US Congress – as a Democrat.

He is among around 30 Christian white clergy – pastors, seminary students and other faith leaders – known to be potential Democratic candidates in next year’s midterm elections, including a dozen who are already in the race. While stressing the separation of church and state, many say that on a personal level their faith is calling them into the political arena.

The trend marks a break from a traditional racial divide. Whereas Black pastors who run for office are typically Democrats, their white counterparts are usually Republicans, reflecting the strength of the religious right and the party’s dominance among evangelical voters.

From Texas and Iowa to Arkansas, faith leaders are wading into politics to counter the rise of Christian nationalism

“But I also think the stereotypes of Republicans being pro-faith are bullshit too. We’re seeing a current administration bastardise faith almost every day. They used the Lord’s Prayer in a propaganda video for what they’re now calling the Department of War. That should have had every single evangelical’s bells and whistles and alarms going off in their head: this is sacrilegious.”

White clergy are deciding to run for office, Ryerse believes, in part as a response to the rise of Christian nationalism and the reality that, according to a Public Religion Research Institute (PRRI) survey, Trump won 85% of the white evangelical vote in last year’s presidential election.

Ryerse said: “We realise, hey, our churches and the people in our churches have been duped by this guy and so rather than hope someone else will clean up the problem, what we’ve seen is a lot of pastors respond with, you know what, I’m going to jump in and I’m going to be a part of the solution.
