"It's how we isolate ourselves. It's one of the reasons a lot of middle Americans didn't vote for Hillary. And bridging the gulf is on us, not them. It requires that we accept certain realities. A person can still be 'on the team' even if they think the minimum wage should be raised only to $10, or don't consider the placement of the crèche on the courthouse square for two weeks in December a constitutional crisis, or haven't yet figured out how they feel about transgender bathrooms. If we don't find a way to welcome them, they'll go to the other side. That isn't how majorities are built. Unfortunately, it's how elections are lost."
Michael Tomasky at The New Republic argues that "this chasm between elite liberals and middle America is liberalism's biggest problem."
Kevin Drum at Mother Jones agrees.
