I wish to welcome Josh Blackman as a guest blogger this week Josh is an Assistant Professor of Law at the South Texas College of Law, and author of Unprecedented: The Constitutional Challenge to Obamacare. It is a marvelous book describing the constitutional challenge to the Affordable Care Act based on extensive interviews with all the major players. It taught me a lot about the case I didn’t know, and is remarkably even handed. (Disclosure: I wrote the Preface to the book.) In his blogging this week, Josh will be offering tidbits about the litigation.
