The city has published the final list of candidates in this year's city election . Yesterday was the deadline for submitting nomination petition signatures. Only the candidates listed in red have qualified for the ballot.There will be a citywide preliminary election for Mayor on September 19, because two candidates, Payton Corbett and Kenneth Van Buskirk, are challenging Mayor Joe Curtatone. Preliminary mayoral elections have become rare in recent years, but Mayor Joe ousted our previous mayor, Dorothy Kelly Gay, in a 2003 preliminary election. The last preliminary election for mayor happened in 2007. The top two finishers in the preliminary go on to run against each other in the November 7 general election.Ward 1 residents will also have a preliminary election for School Committee. Three candidates are running to replace incumbent Stephen Roix, who is not seeking re-election.All four current aldermen-at-large are seeking re-election, along with challengers Stephanie Hirsch, Will Mbah, and Kevin Tarpley (a former Ward 2 alderman). Since there are fewer than nine candidates, there will not be a preliminary election for alderman-at-large.Ward Four alderman-at-large Tony Lafuente is not seeking re-election. Two candidates are running to replace him. All other aldermen-at-large are running for re-election, and they have challengers in wards 1, 2, and 3.
