Wickard eventually mutated into
Raich which expanded the commerce clause to include actively prohibiting anything which _allegedly_ REDUCED demand in an ILLEGAL interstate market. This in turn bounced
Stewart, which addressed firearms which never were and never could be in interstate commerce (machineguns built by a felon); SCOTUS refused
Stewart citing applicabilty of the just-decided
Raich.
So what happens when SCOTUS tells TN "no, you can't exempt that"?
