Aaron Blake of the Washington Post writes that Donald Trump’s appointment of Breitbart Executive Chairman Stephen K. Bannon to CEO of his presidential campaign “will give the establishment GOP heartburn.”

From the Washington Post:

Donald Trump has assured us many times in recent days that he isn’t going to change his approach to the 2016 election. “I don’t want to change,” he told WKBT-TV in Wisconsin on Tuesday. “Everyone talks about, ‘Oh, well you’re going to pivot.’ I don’t want to pivot.”

And if there’s anything that could symbolize that resolve, it’s his decision to bring the head of Breitbart News on board as campaign CEO.

“Our vision — Andrew’s vision — was always to build a global, center-right, populist, anti-establishment news site,” Bannon said.

[Bloomberg’s Joshua] Green also reported that Andrew Breitbart had “described Bannon, with sincere admiration, as the Leni Riefenstahl of the Tea Party movement.”

And therein lies the problem for a Republican establishment that would like Trump to clean up his act. For non-students of history, Riefenstahl was a filmmaker and Nazi propagandist. The Post’s Robert Costa reports that Bannon has encouraged Trump to run as “an unabashed nationalist” — the kind of direction that will give the establishment GOP heartburn.
