David French of National Review Online explores the political impact of radical progressives. He focuses on the Overton window, “the acceptable range of political discourse on any given topic.”

We’re no longer fighting about “the” Overton window. Our differences have grown so profound that “the” window has broken. We’ve got two windows now. One for red. One for blue. …

… There is a difference, I believe, between progressives and conservatives. Given their control of the academy, legacy media, and Hollywood — along with their intense geographical concentration in large, urban enclaves — progressives are not only racing further to the left, they’re also deceiving themselves about their cultural strength.

They think they’re “winning” when they’ve really moved mainly themselves. The other window either remains unmoved or moves right in response. Arguments on the far-left side of the blue Overton window (like campus temper tantrums) are greeted with complete incredulity and open mockery on the right.

In fact, even progressive conventional wisdom (such as the notion that a man can become a woman) is at best on the far-left edge of the Republican Overton window. At best. Similarly, I’d challenge a Republican to walk into a Brooklyn coffee shop and find a single person who didn’t think you were a violent bigot for believing that Caitlyn Jenner is still a man and that the Second Amendment alone grants you the right to carry a weapon.

We may have exhausted all the “why Trump won” arguments, so I won’t go there. But I will say that the notion that one Overton community will govern the other is increasingly infuriating and even terrifying to the losers of national political contests.
