Paul Krugman: The Time-Loop Party

By now everyone who follows politics knows about Marco Rubio’s software-glitch performance in Saturday’s Republican debate. (I’d say broken-record performance, but that would be showing my age.) Not only did he respond to a challenge from Chris Christie about his lack of achievements by repeating, verbatim, the same line from his stump speech he had used a moment earlier; when Mr. Christie mocked his canned delivery, he repeated the same line yet again.

In other news, last week — on Groundhog Day, to be precise — Republicans in the House of Representatives cast what everyone knew was a purely symbolic, substance-free vote to repeal Obamacare. It was the 63rd time they’ve done so.
