For years they've supported the worst know-nothing bombast of Drudge and Limbaugh, the casual reality distortion of Fox News, and the resentment-based appeals of people like Newt Gingrich and Sarah Palin. And they've turned a blind eye to even worse: birthers, Agenda 21 lunacy, Cliven Bundy's army, and much, much more. It was handy at the time, and helped win a few elections. But now the outrage-based mob they've nurtured has come back to haunt them — and unsurprisingly, it turns out not to care all that much about the debating-hall nuances of Edmund Burke and Russell Kirk. They just want to kick out the wetbacks and get back at those smug liberals who make fun of them.
