On Tuesday evening, establishment Republican consultant Rick Wilson said the GOP establishment donor class must find a way to “put a bullet” in GOP frontrunner Donald Trump.

In an interview with MSNBC’s Chris Hayes, Wilson conceded that “Trump is still a very powerful force right now” because he appeals to part of the of the conservative base that Wilson said was activated by his “nativist” message. Wilson insisted that the donor class “can’t just sit back on the sidelines and say, ‘oh well, don’t worry, this will all work itself out.’”

“They’re still going to have to go out and put a bullet in Donald Trump,” Wilson said. “And that’s a fact.”

Republican establishment figures who have underestimated Trump since he entered the race are reportedly looking to raise millions to try to derail Trump and knock him out of the race. Wilson added that the Republican establishment must figure out a way to find a candidate who can successfully “post up” against Hillary Clinton because “neither Donald Trump or Ben Carson is ready to go up against the Clinton machine. Wilson claimed that Trump and Carson are “obviously not ready for primetime.”

Wilson, who tried to use the disgusting rape threat made against his daughter to score political points against Breitbart News and Breitbart News Editor-at-Large John Nolte, has denigrated Trump and his supporters throughout the election cycle.

During a September CNN interview, Wilson told Erin Burnett that Trump could “eat a live baby on television” and Trump’s supporters “would think it’s the greatest thing in America.” He has also demeaned Trump’s supporters as “low-information” rubes and has likened them to “post-rational” conspiracy theorists.

In an interview with CNN’s Don Lemon, Wilson said Trump’s message “doesn’t have to make sense” for his supporters to back him and compared Trump to someone who is a conspiracy theorist like “your cranky uncle at Thanksgiving” who always has a theory about the Bilderbergers or the World Bank, or the IMF, or the Trilateral Commission.”

Trump has never referred to any of these entities on the stump–all Trump has said is that America has signed unfair trade deals in which America’s stupid leaders let other countries take advantage of the U.S. to the detriment of American workers. But Wilson claimed that Trump has a “very strange, sort of parochial, old-fashioned view of the world and the international economy.”

“And this thing, I’m going to bring back the jobs from China. OK. The $2-an-hour jobs making wire harnesses for computers. It’s just a fantasy,” Wilson said.

Trump has been like Teflon in this election cycle because so many Americans are fed up with out-of-touch establishment consultants like Wilson and their preferred candidates like Jeb Bush and Marco Rubio. Wilson and his ilk charge candidates hefty sums to “advise” them on how to appeal “regular Americans,” but he and the consultant class have not only shown that they are clueless about independent voters and Reagan Democrats who determine elections, but, perhaps more disturbingly, revealed how much disdain and contempt they have for blue-collar Americans of all backgrounds who are not versed in the lingo of the tactician class.

GOP establishment consultants often preach that “politics is about addition” when taking shots at conservatives for rhetoric that they do not like or think will turn off “independents,” but those like Wilson have been quick to attack Trump and his supporters with inflammatory language that they would never tolerate from conservative candidates and their grassroots supporters.
