Are Iowa Evangelicals on the Trump Train? These Pastors Offer Clues.

Before he clinched the 2016 Republican nomination, won the presidency and remade the party in his nativist, norm-shattering image, Donald J. Trump lost the Iowa caucuses to a conservative Texan who had consolidated the support of evangelical leaders and voters in the state.

Eight years later, Mr. Trump is favored for victory in the Iowa caucuses on Monday, fueled by evangelical voters who have become among his most reliable supporters — and a more organized Iowa campaign effort that includes courting the kinds of religious leaders who helped propel Senator Ted Cruz’s victory in 2016.

Of Mr. Trump’s rivals, Gov.
