The thing is - electors had free will but were also chosen by the winning political party to cast the vote so they were politically loyal to whom was being elected.
Some states have changed this to make it an official government office chosen by committee - in those cases electors shouldnt have free will.
Regardless this is ultimately a stupid facile argument and shows just how far power has been removed from the people and shifted into government control where tyrants and their brown shirts control policy.
Wrong!
