Influential radio 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. 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.”

A Monmouth University poll released Aug. 31 found that retired neurosurgeon Ben Carson holds the edge in the Hawkeye State among evangelicals with 29 percent support, compared to Trump’s 23 percent support.

The same survey has Carson and Trump tied for the overall lead in the state at 23 percent support each, followed by former Hewlett-Packard CEO Carly Fiorina in third with 10 percent support, Cruz with 9 percent support and Wisconsin Gov. Scott Walker with 7 percent support.
