A third well-known candidate entered the special election today when Councilman David Alvarez announced he was running for mayor.
In a tweet, Alvarez said, "I'm in. Filed my intent to run."
In his social media post, Alvarez, a Democrat who represents district 8, said San Diego needs a mayor who cares about the future of working families and neighborhoods.
Alvarez joins former Assemblyman Nathan Fletcher, also a Democrat, and Republican Councilman Kevin Faulconer as the major contenders for the city's top seat. Former City Attorney Mike Aguirre also announced his intention to run.
There are now at least 20 people vying for the job of mayor. Candidates have until Sept. 20 to file their paperwork for the election.
The special election for mayor comes after Mayor Bob Filner resigned amid multiple allegations of unwanted sexual advances and one lawsuit from a city employee alleging sexual harassment. Voters will go to the polls on Nov. 19.
