The Commerce Clause describes an enumerated power listed in the United States Constitution (Article I, Section 8, Clause 3). The clause states that the United States Congress shall have power “To regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes.”
The original INTENT of the CC was to remove substantive hindrances to commerce between states. This goes WAY beyond that.
Does seem to give him the authority to do this. True enough.
We'll hope for the best.
