IIRC Wickard was one of the decisions handed down when the Supreme Court assumed lap dog status after FDR [spit] threatened to add three more justices because they correctly were finding his New Steal pogroms unConstitutional. So, an illegitimate decision reached for illegitimate reasons to protect illegitimate programs out of fear of an illegitimate person.
Time to use the ‘living document’ tactic against them.
Wichard was then, this is now. We no longer accept that what a person does on their own property effects interstate commerce absent substantial evidence of that effect.
