So much for “state’s rights.”

Irony & Stephen being an arch-ghoul notwithstanding, federal law does supercede state law (Art 6 Sec 2). Like, Nebraska couldn’t just legalize murder. It’s still federally illegal. They could stop enforcing that law, but it’d still be illegal and the federal gov’t could take action.

federal law does supercede state law (Art 6 Sec 2)

Only to the extent that the Federal law is constitutional (ie within its powers) and valid

That’s a fair point. But it would need to be argued in the courts.

And “constitutionality” is defined by the Supreme Court…

Doh!
