Nice idea, but neither Trump nor Congress can repeal or invalidate state firearms laws.
It's going to be up to the SCOTUS to do that, and that's years from now.
So one might think, at least at first blush. Upon reflection, though, I'm not so sure:
Amendment 2 of the United States Constitution confers certain federal, constitutional rights on citizens of the United States.
Amendment 14, Section 1 of the Constitution provides, in part: "No state shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States . . . "
Amendment 14, Section 5 provides: "The Congress shall have power to enforce, by appropriate legislation, the provisions of this article."
In fact, Section 5 is the constitutional basis for any number of so-called civil rights statutes enacted by Congress, many of which have been used to achieve judicial declarations of the invalidity of contrary state and local enactments.
Arguably, Section 5 means a tad less than it appears to say. Certainly, Congress cannot
create a new federal right, and the extent to which Congress can
define the parameters of an existing constitutional right are a tad murky. See
City of Boerne v.
Flores, 521 U.S. 507 (1997). But these limitations do not mean that, assuming a carefully drafted and confined statutory remedy for state and local violations of Second Amendment rights, Congress is entirely toothless in this context. See
Oregon v.
Mitchell, 400 U.S. 112 (1970) (striking down state literacy tests for voting, which Congress had found could be and often were improperly administered).
Now, I'm not necessarily saying that federalizing pistol permits would be a good idea. Neither am I prepared to bet my lunch money that, even as it will be constituted starting this January, such a proposal would have a chance of being enacted. I rise, rather, merely to point out that in constitutional terms, a federal statutory enforceent of certain constitutional gun rights does not necessarily implicate states rights, the 10th Amendment, or principles of federalism.
