Sorry, but the term "Constitutional principles" is an oxymoron. The Declaration, for example, stated that all men are created equal, in terms of rights, but the Constitution (in true Animal Farm fashion) then claimed to give some of those "equal" people the right to forcibly rob all the other "equal" people. Yes, the power of "taxation" was supposed to be significantly limited in several ways, but it was still the power to steal. How does that match the notion of everyone being "created equal," and the only purpose of "government" being to protect rights? It doesn't. It is a direct, blatant, glaring contradiction. And working hard to get us back to a glaring contradiction, as the Constitution Party does, is not a good idea.
2) The Constitution cannot consist of unwaivering principles, because it was designed to be amended. If the control freaks go through the official, formal procedure of "amending" out all those pesky limitations, then what? Then totalitarianism will become "Constitutional," and what would the Constitution Party say then? The truth is, instead of being some perfect expression of truth incarnate, the Constitution started as a huge, self-contradictory, illegitimate compromise, between some people who actually wanted individual freedom, and others who wanted to rule.
3) People have been so thoroughly trained to believe that freedom must be "legalized" before it is good, that they remain determined to bash their heads against the wall of the "political process" to achieve it. This is true of the Constitution Party and many others. If you believe in inalienable rights, why are you asking the politicians for "legislative" permission to do things? For example, the Bill of Rights (the first ten amendments to the Constitution) describes things that "government" was not supposed to do at all--yet they do them on a regular basis. If your answer is to try to elect people who will change that, you're implicitly conceding that they weren't inalienable rights to begin with. By definition, if you need a "law" to allow something, it's not a "right." So, aside from the contradictions in the Constitution itself, if you actually believed in the "inalienability" of rights described therein, you'd be doing whatever you could--including things the politicians have deemed "illegal"--to defend those rights. Begging the master to let you speak your mind, or to let you be armed, or to spare you from random searches and interrogations, and so on, carries with it the implied message that you need the master's permission to do those things. As a result, trying to regain "rights" via the political process is an inherent contradiction.
4) The American people, having been thoroughly indoctrinated into the cult of statism and the worship of collectivism, don't want what the Constitution describes. (Neither do I, but for very different reasons.) By playing the "democracy" game, the Constitution Party is basically conceding that what the majority wants is what matters. Yes, they would like the majority to agree with them, but since it doesn't, why play a game (i.e., voting) that merely reinforces the looney notion that the majority has the right to rule in any way it sees fit (or in any way it's duped into supporting)?
5) The Constitution created the monster you see now. No, this is not what it described, but (just like the theory of communism) that's what it actually resulted in in the real world. So, pretending for a moment that there is the slightest chance in hell that the American people would even support going back to the Constitution, why would anyone expect it to turn out differently next time?
(Incidentally, the ink was still wet on the Constitution when the principles described therein were trashed. If you haven't before, do a little research on the crushing of the Whiskey Rebellion, the Louisiana Purchase, and the Aliens and Sedition Acts, for starters. Each of the first three "Presidents" trashed the Constitution, and any principles it pretended to be founded upon. Pretty much every President since then has done the same, though some more dramatically than others.)
Again, I eagerly await the hate mail, since I just bashed what many treat as infallible, holy doctrine: the Constitution. But before you tell me how stupid/evil/insane I am, consider this:
(P.S. For those of you who think that at least a step toward freedom would be an improvement, I sympathize a bit. However, when has that ever actually happened? And why is there any reason to expect it to happen now, because of any "political" efforts?)
