Are the rules on alternate electors different in each state? I wonder.
As in who can legally submit them and does any state official have to agree to the submission, or not.
I think you unknowingly answered the question with your question. Rules and laws are different things.
Are there RICO laws for preparing to contest an election? No!
Are there rules for contesting elections? Yes.
This case is ridiculous on the merits, and must be tossed into the trash bin from whence it came.
