It’s not your power unless the Constitution grants it to you.
We're kind of past that point. The Constitution was a mere hologram of liberty, as Kenneth Royce put it. It did not in fact protect us from the depredations of government. It is time for something else. I don't know what will do the trick. Those smarter than me will have to say what, but I can see that voting and screaming "The Constitution!" all the time doesn't work.
