It seems that Obama is saying that the personal mandate is a “political issue or question”, that the issue constitutionally should be resolved by branches of the government other than the Court. It has been argued recently in reapportionment cases and Nixon vs US (1995), but not successfully.
That's interesting. I can see that now. My takeaway was how heavily he leaned on the weak 'presumed constitutionality' in legislation.
But the real sub rosa fear that he's transmitting, is that an Obamacare overturn draws the line (and perhaps the curtain) on the wretched supraconstitutional abuse the Commerce Clause has suffered at the hands of Leftists desperate to shackle the US to the chains of Eurosocialism.
