The Constitution provides within itself the only means by which its protections and limits on coercive government power can be changed. Thomas Jefferson described "the People's" power as "chains", on elected officials, as in his admonition, ". . . bind them down from mischief by the chains of the Constitution."
This President chafes and complains that the Constitution doesn't allow him to do what he wants to do, but then he goes ahead with actions which tests the limits of Executive power by enacting policies, properly defined, that amount to "legislating" instead of "executing" that which the Legislative Branch legislates.
By doing so, he and his fellow "progressives" rely on what they believe to be the ignorance of "the People," described by Justice Story ("Commentaries on the Constitution . . . .") as being "the only KEEPERS" of that Constitution.
The time has come for citizens to study the principles underlying their Constitution--principles designed to leave an orderly means of control of the men and women they elect to serve them.
George III was a mere figurehead compared to the modern-day Presidents. And he didn't make the citizens pay for his trips to fundraisers.
