Attempting a rhetorical flourish worthy of the current administration, I wouldn’t call Bush’s reign a dictatorship, nor a monarchy, simply, “extra-Constitutional.”
Think of it, it’s perfect! People who don’t really know what it means would say, “Well, I guess them fellahs’re extra protective of that thar’ Constitution thingy.” All the while, they could say they were telling the truth about their treatment of that hallowed document.
