    From TFA:

    The same goes for the Senate’s vote to block California’s program banning gas-guzzlers by 2035. The state has the power to do this under a long-standing waiver to the Clean Air Act allowing it to set its own emissions standards.

    In this case, California was utilizing a federal law to effectively ban ICE vehicles and Congress closed that “loop hole.”

    State laws are wholly operating within federal law, insofar as the federal government has the authority granted to it by the constitution to do so. Anything not granted to the federal government is defacto state territory according to their constitution.

    I’m not the guy to really explain your specific questions though. Most of that has to do with a long history of legal precedent and constitutional law over hundreds of years.
