How the Politically Unthinkable Can Become Mainstream

You may have heard about the Overton window, and that’s not about to stop. With the political landscape shifting in sometimes startling ways, what was once an obscure idea has gained broader relevance.

But while the term has been bandied about lately, it hasn’t always been by people who know what they’re talking about. And it’s important to get this right. You’ve probably noticed that policies once dismissed out of hand — from “Medicare for all” to a 70 percent top tax rate; from sweeping action on climate change to abolishing Immigration and Customs Enforcement — are being discussed in mainstream circles now.

The Overton window is a useful way to understand what’s happening. CONT.
