There's a book written back in the 1960s that deals with this phenomenon: The Revolution of the Saints: A Study in the Origins of Radical Politics, written by Michael Walzer [1], and which book in my view described the current political climate from most of the world pretty spot on. I don't live in the States, but in Eastern Europe, but I still can see firsthand new parties/new people who have entered into politics (they're mostly new) who see themselves as "saints", anyone who doesn't think like them is either corrupt or, generally speaking, not on the good side of history.
