Let’s be realistic. That is not a hurdle for the Demoncrats. Laws are for the other guys. Demoncrats have slipped in replacement candidates after the deadline before – with the full backing of our “impartial” justice system.
The interesting tweak on this is that whatever fast legalistic move the Demoncrats pull to get their chosen candidate on the ballot may also make it easier for RFK to get on the ballot in all States. Oops!
