The Town's Clerk Marcia L. Parkhurst claims it was an accident which was corrected and did not affect the election outcome. Looked for a political party affiliation on her but wasn't able to find one. Errors such as this were committed by republicans in 2020 though and that didn't seem to be of much consequence anyway. "Oh they were a RINO" or a plant or whatever.
So... accident or deep state government conspiracy...? Choose your own adventure.
