Easy answer, because it's now been fleshed out by our President as a "Cloward-Piven" strategy. In other words, it will be a manufactured crisis, the mother of all such actually, during which, the President will "take charge", thereby demonstrating his "leadership" and (probably) creating an un-Constitutional power grab of the economic (appropriation) reins from Congress.
The Holy Grail for Obama is not taxing the rich, a simple smokescreen for the present, it is to be able to bust the debt-ceiling at will. If he creates a fiscal disaster, he will then tell us that only more "stimulus" spending will see us safely out of the disaster, and so he will order the Treasury to print that money, he will order it spent (likely added to present stimulus law), and we will add another few trillion to the debt.
If the House of Congress finds it's spine, and I'm NOT betting on that, all it can really do is start impeachment proceedings, but the while the (GOP) House might impeach, the (D) Senate won't convict, so that's a stalemate. Bill Clinton was impeached, and it hasn't stopped the (D)emocratic Party from calling him the "elder statesman".
After some time has passed, and with as much delay as can be arranged, Obama will have to face the Supreme Court, which will probably declare that part of the National Debt he created by fiat to be illegal.
Okay, what then?
Nothing, then. Unlike FDR, who actually stopped his stimulus programs when the SCOTUS ordered him to cease and desist, Obama won't stop. Is the SCOTUS going to hold Obama personally responsible? No. Is the SCOTUS going to hold him in contempt and order the US Marshals to arrest him and put him in jail? No, you and I would get that treatment, but Obama won't.
Obama will have ignored the Constitution and the SCOTUS and gotten away with it.
What other part of the Constitution might he ignore next? Hard to say, but all the anti-gun filk would beg him to give similar treatment to the Second Amendment. There's a physical threat to his tyranny there, after all. He might try to muzzle Internet dissent and trash the First Amendment while he's at it. Along the way to trashing those pesky First and Second Amendments in the Bill of Rights, the Fourth and Fifth Amendments will probably go away, too.
Bottom line, by the time 2016 rolls around, there will be NO doubt that Obamalamadingdong intends to stay in office as long as he wants to (read: until he can groom a "Manchurian" candidate who will take his orders), so the (D)emocratic Party will just ignore the election and not even nominate a candidate to replace him.
Blue sky theory? You bet, but it's how some of his advisers think, and Obama himself has never had or expressed an original idea, he IS the product of his advising staff.
Yep, these are Valerie Jarrett's ideas as well as mine, I'd bet on that. We know, to a moral certainty, that what Valerie Jarrett wants, Valerie Jarrett gets. What Valerie Jarrett advises, Obama acts upon.
By this time next month, it will be unlikely that this Nation will be able to be rescued from total tyranny without resort to arms, and that uprising, when and if it occurs, will be a mere blip in history, a "beer-hall putsch", a short interruption in the Greater Glory of Our Glorious Leader.
All Hail, etc.
