But the state-level battles between businesses and evangelicals demonstrate that the Republican Party’s troubles go beyond the concerns over Trump — pointing to a potentially irreconcilable divide between core elements of the GOP base.

Each side remains influential. Evangelical leaders can mobilize large numbers of activists and voters in key states and congressional districts. Corporations, meanwhile, operating in a post-Citizens United world of unlimited political spending, have the ability to put enormous pressure on policymakers.

“You are talking about two portions of the Republican Party who don’t fundamentally understand one another. That’s the bad news,” said Gregg Keller, the former executive director of the American Conservative Union. “The worse news is that they think that they do. What that leads to is further misunderstanding on top of disagreement.”

The anger among evangelicals was especially raw this week after Deal’s veto.
