No, it did not. The establishment of the individual mandate was established as a penalty, not a tax, but the constitutionality of the changes made via executive fiat were not. Don't play stupid with me, you'll be handed your ass.
More rambling, nonsensical shit. The executive office of president is established as managerial, for the purpose of establishing dialogue with congress, he has special powers to convene them in a case of disagreement between them, under Article 2, Sections 2 & 3 of the US Constitution, until such time as the disagreement is satisfied, or he adjourns it to be reconvened at a later date. They used to do those "lock-downs", lock up Capitol Hill until that vital business was complete.
However, Obama is such a piss-poor manager, lacking the ability to make concessions, and arrogant to the point of making a mockery of the office, he wouldn't do that. He can't do that, because he can't stand being challenged on any damned thing. So he relies on executive orders to do the dirty work, orders that are intended to fill in gaps where there is no established avenue of due process. However, he evaded the process, and continues doing so. What you, and other Proggies, call "Obstructionism" was regular business until the middle of the last century, sometimes it took them weeks, in closed session, to work out laws and budgets.
Lawmakers these days don't understand their jobs, and Obama is a main culprit. You
make them sit, you work concessions to close gaps, and you act "Presidential", not like some spoiled, ego-tripping monarch who's afraid to wade in and get his shoes muddy. It's obvious that he's either too lazy or too proud
to do what his predecessors accepted as a matter of course. He had options, he willfully bypassed due process, and he's going to be held accountable for it. Watch and see.
