Nothing the libs would like more than to get rid of Sheriffs - I should say ELECTED Sheriffs. All other law enforcement heads are appointed by the government, city, state, federal. Sheriffs are elected by the people. As such, they are the ONLY law enforcement organization who truly serve the wishes of the citizens in their jurisdiction. Appointed department heads serve the wishes of the government who appointed them.
The libs goal is to remove Sheriffs who don't go along with the "party" line and then replace them with appointed Sheriffs who will enforce any laws the "party" passes, whether they are Constitutional or not. Is it illegal to appoint Sheriffs? Yes. Would that stop libs from doing it? No.
