Paul Krugman: It's All Benghazi

So Representative Kevin McCarthy, who was supposed to succeed John Boehner as speaker of the House, won’t be pursuing the job after all. He would have faced a rough ride both winning the post and handling it under the best of circumstances, thanks to the doomsday caucus — the fairly large bloc of Republicans demanding that the party cut off funds to Planned Parenthood, or kill Obamacare, or anyway damage something liberals like, by shutting down the government and forcing it into default. Sometimes — all too often — there’s no substance under the shouting. And then we need to tell the truth, and say that it’s all Benghazi.
