Mayor Donna D. Holaday and Councilor at Large Richard E. Sullivan Jr. were the top vote-getters in last Tuesday’s preliminary mayoral election, but the field for the final election may not yet be set. City Clerk Richard Jones said that Ward 2 Councilor Richard E. Earls, who finished just 55 votes behind Sullivan, told him he was considering a recount and that Earls’s campaign later stopped by to pick up recount petitions. Only the top two finishers in the preliminary advance to the final election. The recorded tally from Tuesday showed Holaday, who is in her second term, with 1,499 votes to 1,357 for Sullivan and 1,302 for Earls. A total of 4,170, or 31.6 percent, of the city’s 13,196 registered voters turned out for the preliminary. Potentially adding intensity to the final race is that the mayoral term shifts from two years to four years with the new term. Sullivan is a son of the late mayor Richard E. Sullivan and brother of Christopher Sullivan, a former city councilor and interim mayor.
