A wolf in sheep's clothing? Quite possibly... Perhaps the playing of a trump card (in this case, quite literally) is a possible answer: Deputize every legal citizen of the United States as federal officers. This removes all interference at the state level as it concerns firearms laws. Basically it's the same immunity from state law enjoyed by the US Postal Service for its fleets' registration of inspection. As we all know, all presidents have plenary pardon power (we see this time and again each time an administration comes to a close). But, more importantly, they also have the power of appointment. Such an appointment would not require the advice and consent of the Senate (as it is not a principal office). And any interference from the Supreme Court would be barred under the Constitution's Separation of Powers doctrine.
