The main argument of some Constitutionalists is, that Congress has exceeded thier enumerated powers designated in Article 1, sec 8 and read many implied powers in.
Although the Elastic and General welfare clauses are of course interpretive, IMO, Congress at times far exceeds what the Framers envisioned.
If we look at the Preamble to the Bill of Rights:
The conventions of a number of the States having at the time of their adopting the Constitution, expressed a desire, in order to prevent misconstruction or abuse of its powers, that further declaratory and restrictive clauses should be added: And as extending the ground of public confidence in the Government, will best insure the beneficent ends of its institution.
This was a direct statement that the Congress wished the feds to have a limited role in government and leave most of the "general welfare" to the states, as under the doctrine of the "New Federalism".
I have no qualms though about the US SC incorporating the Bill of Rights to the states, as most of it applies now. Though the Vicinage clause does not, states do not have to indict by grand jury, the ecessive bail provision is not applicable to the states.
