PAUL KRUGMAN uses a ridiculous standard to measure the expertise of his conservative opponents. “Political conservatism and serious policy analysis can coexist, and there was a time when they did. Back in the 1980s, after all, health experts at Heritage made a good-faith effort to devise a plan for universal health coverage — and what they came up with was the system now known as Obamacare.”

Yes, Krugman thinks conservatives can be serious — when they come up with ideas he likes.
