You have not done your homework. First of all, that's 'Wickard'. These are 2 of the most important Commerce Clause cases of the last 100 years. They gave fedgov the green light to control health care, the environment, education etc.
Roberts ruling does not touch these cases or the precedents they set. May I ask where you got your info for your assertions? It sounds a lot like a column from Krauthammer on Roberts' 'Brilliant Tactical Maneuver'. He got his facts wrong.
I do not get my info or opinions from other so called commentators, I read and formulate my own..
I actually read the damn thing instead of letting some radio host tell me what to think
In the ruling, starting at page 21, Wickard is brought specifically into this...
Have you read the entire ruling?
by the way, i am not a lawyer, I am a human.. :)
