My coauthor Jonathan Adler and I have been educating state lawmakers about how ObamaCare allows them to block the law’s employer mandate, and to exempt collectively 15 million taxpayers from its individual mandate. So far, 32 states have exercised those powers, exempting all of their employers and 10 million residents from those punitive taxes. In Mother Jones, MIT economics professor Jonathan Gruber calls our interpretation of the law “screwy…nutty…stupid.” (This issue is currently being litigated in Oklahoma.) 

In this Cato video, I challenge Prof. Gruber (and any other supporter of the law) to a debate on the powers Congress grants states under ObamaCare.
