Of course, you are assuming that this regime will respect 2A any more than it has the rest of the Constitution.
No matter how we slice it, these are going to be interesting times.
Well, yes; and Obama has been busily transforming the US military. I think it is now an open question if the military would fire on the US citizenry. Give Obama a little more time, a second term for instance, and the military will shoot US citizens who fight Obama. The Regime will make it look pretty, label it fighting domestic terrorism, etc., but it will happen.
As in the old Chinese curse?
The real question will be if Obama has put in enough of his Leftist henchmen in key positions of power to allow him to get away with what would be, for all intents and purposes, an act of high treason against the United States should he blow of a clear and final judgment of the SCOTUS.
The 2nd Amendment was put there as a final action against tyranny and it may never come to that...
...just nice to have it there if we need it.
