Bonnie Corwin, a Democratic activist who led the calls for Assemblyman Raul Bocanegra’s resignation, is running for Bocanegra’s now-vacant office representing the northeast San Fernando Valley.

Corwin, a Sylmar resident, announced her candidacy in a phone call to a Daily News reporter Tuesday evening.

Two other candidates, Republican Ricardo Benitez and the Green Party’s Steve M. Correa, had filed to run before Bocanegra said Monday he was resigning immediately amid sexual-harassment allegations. With the declaration deadline months away, higher-profile candidates will be expected to join the contest. A special election to fill the California Assembly seat is likely to be scheduled in conjunction with the June 5, 2018 statewide primary, if not earlier.

Corwin, 61, an office manager for a development company, can only improve on the result of her previous bid for public office. She finished last, with less than 1 percent of the votes, among 20 candidates in the Los Angeles City Council District 7 race won by Monica Rodriguez last spring.

Corwin said she filled out candidate paperwork Monday but had decided to seek the Assembly seat before Bocanegra’s resignation, which came a week after Bocanegra announced he would not seek re-election next year.

“I’m honest. I’m transparent. I try to do the right things for the district. Everybody wants certain things a certain way, but I weigh everything and look at he big picture,” Corwin said.

Corwin was an organizer of a small demonstration at Bocanegra’s office on Nov. 1, a few days after the Los Angeles Times reported that Bocanegra had groped a fellow capitol staffer at a Sacramento nightclub in 2009, the first of several harassment accusations against him.
