“[Trump] will isolate you and polarize you and he will take you out,” Beck said. "He will destroy you.

“He is spending money with Tea Party groups and churches and news websites to own them,” the conservative pundit added.

Alinsky’s "Rules for Radicals" has inspired controversy over its principles on income inequality, politics and social justice.

Beck argued that the Republican establishment threatens Trump’s lead in the polls at its own peril.

“[The GOP] is making themselves a horrible, horrible bed [if they] run campaigns against him,” he said of Trump.

Beck said alienating Trump could prompt the businessman to run as a third party presidential candidate next year — something that could benefit Democratic presidential front-runner Hillary Clinton.

“What are the odds that he is a spoiler?” Beck asked of Trump. "What are the odds that he got into this because he’s friends with the Clintons and he’ll get a massive payback?

“Can you imagine if Hillary Clinton gets in because he ran third party?” he continued. "Do you know the favor they’re going to owe him?"

Beck additionally suggested that Trump’s policy stances “make no sense.”

“He doesn’t believe the things that he’s saying,” he said of the New York business mogul, citing his immigration rhetoric.

Trump has repeatedly warned the Republican National Committee he'll consider a third party run if it does not treat him fairly.
