Curiously, Rand Paul may have a point, in an obtuse way. One "expert" anaalyzed it today by commenting... actually, by Roberts going to the length of claiming the bill to come under "tax" instead of an "interstate commerce" question, they went beyond their purview. Technically, to be tried as a tax, there should have been some taxes already paid...and then taken to court.
It makes no difference now, even if the SCOTUS did reach far beyond their bounds, they have made a decision and it will stand; there is nowhere else to go !
....All the more reason we as gun owning Americans, must vote for the one most likely to appoint conservative justices.
