So the author feels that Californai and Oregon are violating Federalist principles....
Sadly I think the Tenth Amendment is dead. If my facts are right, Billy put the wooden stake in its heart when he killed what Reagan had accomplished for Federalism and States Rights.
No, it was killed before that by FDR's handpicked majority in the Wickard case (cited by the majority as justifying the extension of federal powers to everything under the sun). Reagan ramped up the WoD even though there is no Constitutional justification for Congress having such police powers.
It was killed by the 14th Amendment.
