I'm not sure how many other states this will happen in.
RFK got on the ballot in different states using a different parties.
The states have different rules about getting on and off the ballot.
I don't know if this will come up again and if it does, whether or not it will be in a state that matters.
The problem is that the ratfuck operation was supposed to hurt Biden, so they didn't really plan for having to drop out and switch focus.
