The full text of a letter I just sealed and am going to mail off tomorrow:
Dear Commissioner Tartaglione,
I hereby resign my position as Judge of Election in Philadelphia's [number] ward, [number] division, effective immediately. I am resigning because I intend to move out of the division before the November elections.
I greatly appreciate the opportunity to help perform the important civic duty of ensuring fair elections, and I hope I have the chance to do so again in the future.
