This is what I find objectionable, too
Removing an Elector per state law seems legal. Baca case.
Criminalizing his political act of breaking his pledge? Unconstitutional!!!
Article II, section 1, pp 4: “The Congress may determine the Time of chusing the Electors, and the Day on which they shall give their Votes; which Day shall be the same throughout the United States.”
For a State to chose an Elector on any day other than the one appointed by Congress is specifically Unconstitutional. They have to stick with whomever they’ve chosen on the appointed day.
