While I hadn’t before considered that the constitution itself might be the problem, I agree with your assesment of our current status.
Hence my screen name.
What really opened my eyes to our plight several years ago was the realization that most “conservatives” are little more than “liberal-light”. I guess W has a lot to do with that.
In reality, those "conservatives" are more sensible and realistic than the ones clamoring for "limited government", appealing to limits supposedly found in the Constitution. The truth is all questions are merely political, and virtually anything is fair game for national power. Neither side can or will do anything to stop it or change it. Just look at 100 years of commerce clause jurisprudence, for example. Interstate commerce doesn't have to interstate, or commerce. Even Scalia agrees with that notion.
There are very few if any true limits on national power. It's too late to do anything about it either. The only thing to do now is to battle it out constantly on the political field. So you get a "conservative" party. It's like England, with the tories and the labor party. Same deal. All battles are political battles. The Supreme Court is a political organ. Everything is political. The Constitution gives broad, virtually unlimited power to DC, and the parties rule all. Their tenticles extend into every state government. It's a big consolidated mess.
