Upon receipt of an application for a “Presidential Ballot” or “Overseas Ballot” the town clerk shall forthwith notify the registrars of voters of the applicant’s name, with a notation designating him as a person voting for presidential and vice-presidential electors or federal offices only. If the name of a presidential voter who is a former resident appears on the registry list, the registrars shall insert the letters “pf” in the margin preceding his name. The registrars shall prepare a list of names and addresses of presidential voters and overseas electors whose names do not appear on the registry list, for each voting district, which list shall accompany the check list to be used at such election in such district. The registrars shall insert the letters “pf” in the margin of such list of presidential voters preceding the name of each applicant who is a former resident.
