I don't think you have been keeping up with current events. Obama has shredded the Constitution and been allowed to get away with it. He has increasingly been bypassing Congress to "rule" by EO and the Congress is full of so many political cowards that NONE of them are willing to challenge him.
Take off your rose-colored glasses and see this country the way it REALLY is, NOT the way we THINK it is SUPPOSED to be!!!
The Founding Fathers did not envision a time when a corrupt congress and house would back a corrupt president and be supported by a corrupt judiciary and press.
The root cause of this destruction of the Republic and the Constitution is the powerful two party political system.
We now have people in positions of power throughout the government and the press who hold their first allegiance to the Democratis party rather than to the United States of America. in fact with many allegiance to the country and the constitution is far down the list or nonexistant.
As a corallary, one of the reasons the Republican party does not currently muster the kind of political power as the democrats is that a good part of people who comprise the Republican base are solid patriots who hold their allegiance to the nation and the constitution first and foremost. Their allegiance to the party is often far down the list after family, country, religion, ethics, morality, etc., etc. For many there really is no party allegiance - the republicans are usually just the lesser evil of two bad choices.
The two party political system, and specifically the democrat party, is destroying America and there is no remedy on the horizon. In fact, in any attack on the system, hard core Republicans fight reform just as hard as do democrats.
