You can’t just vote for an alternate candidate. That’s a non-viable strategy. In a fptp system (and one that requires owner money) ,you are reliant on party leadership to put forth worthwhile candidates. Democrats should have started grooming the heir apparent on Jan 21, 2020.
Oh, I completely agree. This is way too complicated to fit into simple comment chains. There will be books upon books about this (assuming we’re still allowed to write books in the future).
