It seems to me that a lawyer could craft an argument that lack of “election integrity “ even the suspension of a lack of it violated “equal protection”.
I agree, but without some evidence backing the suspicion, I think a state could easily say, we have sufficient controls and this is a state matter, there is no Federal jusisdiction.
Besides if you have controls for federal elections that are audited, it's highly likely the state will adopt those controls for state elections as well. They wouldn't have two sets of standards, that would easily be attacked by legislators at the state level.
