With federal courts stopping the Biden vaccine mandate, state and local governments run by Democrats will impose their own local mandates instead, New York City being the first to do so.
Unfortunately, state and local vaccine mandates won’t easily be stopped by federal courts as it’s a states’ rights matter, so if California follows suit and makes it illegal for the unvaccinated to work in the state, and they still refuse to get vaccinated, they’ll have little choice but to move out of state.
