It is not necessary or helpful to focus on the sort of general concepts to which you allude; although I will certainly acknowledge that in all of its functions, it looks to a maximum level of individual responsibility in order for our system to work. And that is certainly not inconsistent with the philosophic claim that you make. But you are trying to over-explain, what is clear without looking for some structure that may be generally, though not necessarily inevitably, consistent.
But Santorum has been trying to explain away the fact that he really does not recognize the rights of States, local communities, local courts, and individuals, to make decisions with which he does not agree. He may think that limitations on central authority are a good thing; he cannot be trusted to always recognize them.
Again, to specifically illustrate my point, consider the fact that he was one of those who supported the Federal intrusion into the Schiaavo case, which reflected extremely flawed judgment--both Constitutional & tactical, for that matter. (See Schiavo Case.)

Never heard of the Constitution I guess, since you seem intent on proving your ignorance of it. WE know what the Tenth was about, but the Fed has stomped all over it, you offer nothing but homilies unless you are prepared to take up arms against the Fed.
