John McClaughry: American politics gone insane

Editor’s note: This commentary is by John McClaughry, the vice president of the Ethan Allen Institute.
Jonathan Rauch is a senior fellow at the liberal-leaning Brookings Institution in Washington. He is himself a bona fide liberal, or at least, what passed for a thinking liberal a decade ago. He is a sharp commentator on American politics, and has given us a brilliant and timely essay in the July-August issue of The Atlantic entitled “How American Politics Went Insane.”
