CHAIT: New secret history of the Obamacare deniers. "Lots and lots of people followed the Affordable Care Act really closely. If the federal exchanges were intended not as a backup but as a punishment, denying their customers tax credits, it would have been a huge deal. People would have known about it. The Obama administration would have publicized the threat. This enormously consequential policy decision would be the subject of thousands of news stories and public comments. The news would not be confined to one economist speaking about it a couple of years later." Jonathan Chait in New York Magazine.
