It’s hard for me to believe that the Supreme Court will rule for the plaintiffs in Burwell v. King: The Court has itself already rewritten Obamacare at least as radically as it would have to do to find for the administration. What happens, though, if the Court does the right thing? Tax credits then won’t be available for millions of people on the exchanges in 36 states. Democrats will demand that Congress restore those credits. Over at Bloomberg, I offer some thoughts on how Republicans should respond in that eventuality–and how they should prepare for it now.
