The biggest problem with liberal cities dying, is that, the people who voted in those cities helped to create the messes by electing liberals who only know how to destroy any place they control.
The bigger than ‘biggest problem, is that, those same voters who helped to destroy those cities, will be on the move once those cities begin to rot, and when they move, they bring with them the same ideas and voting records to their new places, and thus, they begin to destroy the new places they move to. Witness to that is how Texas and Florida are trending purple, and might eventually turn blue, and when that happens, where do the red-state citizens move to? Liberalism doesn’t stop until every place it visits is dead.
If they could realize they were the cause they could reverse the damage and stay put.
Progressivism is a socialist disease, it’s transmitted by nitwits.
Add GA to that list. Abrams came way to close to winning in the Peach state.
