Ill bet that two thirds to three quarters of everything the federal government currently does is outside the bounds of the Constitution.
"Liberty and security in government depend not on the limits, which the rulers may please to assign to the exercise of their own powers, but on the boundaries, within which their powers are circumscribed by the constitution. With us, the powers of magistrates, call them by whatever name you please, are the grants of the people . . . The supreme power is in them; and in them, even when a constitution is formed, and government is in operation, the supreme power still remains. A portion of their authority they, indeed, delegate; but they delegate that portion in whatever manner, in whatever measure, for whatever time, to whatever persons, and on whatever conditions they choose to fix."
U.S. Supreme Court Justice James Wilson (Lectures, 1790-1791)
