The commerce clause was intended ONLY to ensure that the several States did not impede interstate commerce by adding such things as tariffs to goods passing through them from other states. Read the Federalist papers and the Founders’ own words on the topic. The abortion we know as the commerce clause today was handed to us by the “modern progressive” POS, Teddy Roosevelt, who was clearly cut from the same big government mold as his kinsman, Frank.
The war on some drugs also started under the reign of the racist, socialist Woody Wilson, as a means of controlling the ethnic minorities in the country. Why alleged “small government conservatives” still favor this abomination is a mystery to me. Except that you are neither conservative nor in favor of small, Constitutional government, are you?
It was then, and is now, all about control over others, something utterly anathema to people who revere the Constitutional Republic the Founders tried to give us.
Where does the Constitution require the SCOTUS to rule based on "intent?" Answer: It doesn't. And anyway, your opinion means diddly. The SCOTUS gets the last word, and they've spoken. CSA is constitutional. Pass an amendment if you don't like it.
