Author Stephen King said Monday that Ted Cruz's religion makes him less electable than Donald Trump.

"I actually think Trump, in the end, would be more electable than Cruz because Cruz is a fundamentalist Christian and it would almost be like electing the analog of an Imam — someone whose first guiding principle would be the scripture rather than the Constitution," King told The Daily Beast.

"I don't think [Cruz] could get elected," King continued. "And even if he was able to govern without blowing up the world, could we look at a guy who resembles a cable game show host for four years? He has that awful plastered-down hair and everything."

But while King prefers Trump over Cruz, he also said he's shocked Trump has made it so far.

"Trump leaves me speechless," King said. "When he came down that escalator to announce that he was going to run for president, I thought to myself that it was a smart joke, and it was a way of basically renewing his brand, refreshing himself in the press, and getting to the forefront. I figured he would run for a while, then drop out, and that would be the end of it ... At this point, he's said 40 different things that would have gotten him laughed out of the race if he wasn't so outrageous."

The Shawshank Redemption author called Trump "bulletproof" for his ability to say increasingly outrageous things without losing any momentum in the polls.

Though he is not rooting for the billionaire mogul's presidential bid, he said he would no longer be surprised if he became the Republican nominee.

"Will he get nominated? I would've said the idea is ridiculous even four months ago, but now I'm not so sure," King said. "Then people are saying that if he does get nominated, he'd never get elected, and I'm saying, well, hopefully that won't happen. But who knows?"
