Here's the deal...this ruling actually puts limits on the Commerce Clause. With today's ruling claiming that the mandate was unconstitutional, but as a tax can stand, Chief Justice Roberts is creating precedent that opponents of using the Commerce Clause as a catch-all to provide ever widening social services is a doomed idea. According to USSC watchers:
The rejection of the Commerce Clause and Nec. and Proper Clause should be understood as a major blow to Congress’s authority to pass social welfare laws. Using the tax code — especially in the current political environment — to promote social welfare is going to be a very chancy proposition.
Roberts gave up on ACA (which can, and hopefully will be repealed) to create that precedence.
I think this is a GOOD thing.
