San Diego County Supervisor Ron Roberts, a Republican, said he will instead run for reelection.
Former Councilman Carl DeMaio, who lost to Filner in the November runoff, said he will instead continue his bid for the GOP nomination for Congress to face Rep. Scott Peters (D-San Diego).
Acting Mayor Todd Gloria, a Democrat, said he will instead spend the next few months attempting to clean up the problems left behind by Filner. As City Council president, Gloria took over most of the mayor's powers once Filner departed.
"It has become clear to me that the problems left by Bob Filner are substantial and serious," Gloria said.
Filner, 70, a Democrat, resigned effective Friday after weeks of accusations that he had sexually harassed women. His resignation was a bargain with the City Council in exchange for the city paying his legal bills in a lawsuit filed by a former staff member.
