McCain very wrong on basics of American Government

After watching "The View" session I was struck that McCain was completely mistaken on a basic point of our system and how it operates.

McCain: “My interpretation of the Constitution of the United States is that the United States Supreme Court enforces the Constitution of the United States and does not legislate nor invent areas that are responsibilities, according to the Constitution, of the legislative branch.”

Well that's just wrong! And I'm shocked that nobody is talking about it. Maybe its because most Americans have a very slim notion themselves about how our system works.

He's partly right, that the Supreme Court is not empowered to legislate. But any reasonable person would assume that after over 20 years in the Senate he would understand perfectly that the SC *interprets* the constitution, not "enforces". The enforcement duty is on the Executive branch of government, which is of course headed by President, who swears to uphold the decisions of the Court.

Either he's really dumb, too old and going senile, or the stress of the campaign is starting to get to him. I guess it's the latter and that he was merely confused and fumbling. Which worries me even more seeing how POTUS has to be about the most stressful and demanding job on Earth.
