Unless a state has American citizen requirements with a photo id, then I would claim that every local, state, and federally elected official is illegitimate. People who aren't citizens vote. People who are dead vote. People who don't exist vote. Ballots are photocopied and counted as legitimate votes.
No one in congress or holding elected office anywhere in this country can prove that they won an election where American citizens (living) and only American citizens voted for them and that their votes were counted correctly, one time only, for what and whom they voted for.
Consent of the governed? Not even close. It's all illegitimate. All of it.
