While I see this comment as unnecessarily partisan, I agree in principle. The US Constitution's limits on federal authority have been being weakened since the day it was written.

Or, in the words of Lysander Spooner: "But whether the Constitution really be one thing, or another, this much is certain - that it has either authorized such a government as we have had, or has been powerless to prevent it. In either case, it is unfit to exist."
