When elected officials take office they pledge to protect the Constitution from all enemies, foreign and domestic. Then they immediately break that oath by not recognizing that almost every thing the federal government does is in direct violation of the Constitution, and trying to stop it. In direct violation, but sanctioned (wink-wink) by federal courts.
How can you protect the Constitution from all enemies foreign and domestic when some of the worst domestic enemies have placed themselves in charge of deciding what the Constitution means? Whether or not the Constitution is worth defending is another matter. As has been said, either it established this governmental monstrosity we now suffer under, or it did nothing to stop it. Fortunately "freedom" does not depend on a piece of paper, but on each of us as individuals. Freedom is ours to take and live, if we will only do it. Pay no attention to the black-robed gremlins of the court. Let them paint themselves into a corner with their pronouncements-from-on-high. Just get on with the business of living free from coercion.
