Influential radio show host Steve Deace says he will quit his job if Donald Trump carries the evangelical vote in the Iowa Caucus.

“If Donald Trump gets 32% of the evangelical vote in Iowa on Feb. 1 I will quit my job,” Deace tweeted on Thursday, responding to someone who referenced a poll. “Not happening.”

Deace, a prominent Iowan conservative, has previously endorsed Sen. Ted Cruz (R-Texas) in the GOP primary.

“In my view, he’s what we’ve been waiting for,” Deace said. “He’s an end to the false choice between principles and electability.”
