Lol. They’ve only ever used “states rights” like “small gubberment”; as a means to impose their will on the largest scale they currently hold power. As soon as they gain the upper hand and can impose their will via a higher government (or regulator) — such as imposing their will on local governments via state law, or imposing their will on states via federal law (or the EPA) — they don’t give it a second thought.
This is how fascists and authoritarians operate. They lie, because words mean nothing to them but a means to achieve authoritarian rule… They don’t stop at the national level either.
