Presently the charter provides that on the fourth Tuesday preceding every regular city election a preliminary election shall be held for the purpose of nominating candidates for the city's regular election which is held on the first Tuesday following the first Monday in November in each odd-numbered year. This amendment will permit the preliminary election to be held on the third Tuesday of September preceding every regular city election. Such earlier date for the holding of the preliminary election is necessary to give the Election Commission sufficient time to prepare the ballots for the regular election.
