Of course it's Constitutional. Unenumerated powers abound in the Constitution. The Constitution empowers Congress to " provide for the common Defence and general Welfare of the United States." That allows the government to enact any law it deems "necessary and proper" to carry that power into effect.
And guess what? The same goes for providing for the "general welfare." If the Congress finds a law is "necessary and proper" to "provide for the general welfare of the US", it enacts it. If the president doesn't veto it, it stands. If the SCOTUS does not overturn it, or even better if it affirms the law, it stands forever. And of course, that is anything but "few and defined powers." Thanks for making my case for me.
Only you could contradict himself within a single sentence.
If the general welfare clause means what you say, why did the delegates fight over enumerated powers or include them at all?
The rest of your blather only supports my case made over a period of years at FR. A Constitution which is ignored, it's words twisted into unrecognizable meanings will be our bloody end. It is the fault of the men who committed these crimes, not those who wrote this wonderful document.
