SARASOTA — A five-month campaign to move Sarasota’s spring City Commission elections to the fall has acquired enough signatures for a referendum to be placed on the ballot this fall.

Decide the Date, as the campaign is known, launched a petition in December that obtained 4,732 signatures — 996 more than the required 3,736 signatures needed to put the issue before voters in November. The referendum will ask voters whether they support moving city elections, including primaries and, if needed, runoffs, from March and May of odd years to August and November of even years.
