Overthrow The U.S. Government?

From Mediate.com: During a congressional committee hearing about the constitutional limits imposed on the presidency and the implications of President Barack Obama’s disregard for implementing the Affordable Care Act as written, one expert testified that the consequences of the president’s behavior were potentially grave. He said that the precedent set by Obama could eventually lead to an armed revolt against the federal government.
On Tuesday, Michael Cannon, Cato Institute’s Director of Health Policy Studies, testified before a congressional committee about the dangers of the president’s legal behavior.
“There is one last thing to which the people can resort if the government does not respect the restrains that the constitution places on the government,” Cannon said. “Abraham Lincoln talked about our right to alter our government or our revolutionary right to overthrow it.”
“That is certainly something that no one wants to contemplate,” he continued. “If the people come to believe that the government is no longer constrained by the laws then they will conclude that neither are they.”
“That is a very dangerous sort of thing for the president to do, to wantonly ignore the laws,” Cannon concluded, “to try to impose obligation upon people that the legislature did not approve.”  http://www.mediaite.com/tv/expert-testifies-to-congress-that-obamas-ignoring-laws-could-lead-to-overthrow-of-government/
One thing that pretty much would guarantee an armed revolt is if President Obama would try and run for a third term, like some liberals have suggested.  I don't think he would be stupid enough to do so, but the idea is out there.
Of course, Hillary Clinton would throw a major league hissy fit.
