The problem that I have with "Commerce Clause" based legislation, is that both the Legislature and the Courts have bought into the fallacy that "once in commerce, always in commerce."
The inescapable logic is that once an item is bought by the consumer, it falls out of commerce. The reach of congress does not continue once the item no longer moves in commerce.
Here, the feds have legislated in an area that is wholly a State police power.
Sadly, I am in the minority. Sadder still, this logic does not sway the Courts.
