Glenn Beck said on Sunday that he thinks the Republican Party would be severely damaged if neither of the two presidential front-runners became the GOP nominee.
"I think it would be the end of the GOP," the conservative radio host said on NBC's "Meet the Press."
"We've all gone out. We've been passionate about it ... I really think it has to be one of the two front-runners. I just think people would feel very betrayed."
He said people like Democratic presidential candidate Sen.

"That's something we don't want to add fuel to," he said. "We don't want to play into the anger and hatred and vitriol."  
He said a Trump nomination would be "disastrous" but added that the billionaire must be the nominee if he wins the necessary number of delegates.
"It can't go to dirty politics," he said.
