Today’s Republican Party is enslaved to Movement Conservatism, and Trump trumpets the rhetoric of that movement in crude sound bites.
Why is Donald Trump so popular? He has captured the moment when voters recognize that Republican political rhetoric has nothing in common with reality. Trump brings rhetoric and reality together in a cartoon caricature of a Republican politician that anyone can understand. That gives him a vital role in history. He is the perfect exorcist to drive a stake through the heart of the modern Republican Party. But he is not the first in history to perform this operation. The same crisis hit the party in the 1890s.
