So this may be a good time to remember that in a key sense, Trump happened because a well-established, real-life mechanism that was in the best position to prevent a Trump presidency failed. That institution was the Republican Party.

It is not entirely true that Trump engineered a “hostile takeover” of the GOP, provided that the party is defined more broadly than elected officials and party insiders. As Conor Friedersdorf wrote last year in the Atlantic: “the elements of the party that sent pro-Trump cues or Trump is at least acceptable’ signals to primary voters—Rush Limbaugh, Sarah Palin, Ben Carson, Chris Christie, Breitbart.com, The Drudge Report, The New York Post, Bill O’Reilly, Sean Hannity, Ann Coulter, Jeff Sessions, Rick Scott, Jan Brewer, Joe Arpaio—are simply more powerful, relative to National Review, Mitt Romney, John McCain, and other ‘Trump is unacceptable’ forces, than previously thought.”

What is true, however, is that the governing wing of the party was fully aware that Trump was not to be trusted with the levers of power. In January of last year, National Review devoted an entire issue to a symposium where 22 prominent Republicans and conservatives detailed their militant opposition to the candidate Texas Governor Rick Perry—who is now Trump’s energy secretary—called “a cancer” on the American political system. Until his nomination was all but assured, Trump had the backing of a lone Republican senator, Jeff Sessions (who is now his embattled attorney general).
