It’s well established that the federal government can’t press state officials and employees into the service of enforcing federal law.
The upcoming conflict, however, is going to be about a different issue: state and local governments actually interfering with and hindering the enforcement of federal law. I suspect that is going to get smacked down hard on supremacy clause grounds.
My concern is that for blue states, like Oregon, the funding is tied up in federal money. They will withhold and play games and I don't know if Oregon has the "willpower" to avoid mutating their ideals in an effort to keep their kids in school and keep renting houses.
