The Constitution specifies electors only.
For a State to have authority to limit an electors actions, the Constitution would have to grant that authority.
The Constitution does not grant that authority.
A similar scenario that has been sued over and won.
States cannot add additional requirements to federal positions. Such as they cannot prohibit felons from running Federal office.
States are constitutionally charged to appoint electors in a manner of the state legislature’s choosing. Full stop.
The 10th amendment says that where the constitution is silent, the power is reserved to the states or the people.
The question of adding qualifications is the exact opposite. The constitution defines qualifications, and the states cannot add thereto.
The 10th Circuit (and soon the Supreme Court) disagree eith you.
“On the merits of Mr. Baca’s claim, we conclude the state’s removal of
Mr. Baca and nullification of his vote were unconstitutional. As a result, Mr. Baca has stated a claim upon which relief can be granted, and we REVERSE the district court’s dismissal of his claim under rule 12(b)(6). We therefore REMAND to the district court for further proceedings consistent with this opinion.
