Former Assemblyman Ted Lieu, D-Torrance, has been racking up endorsements in his bid to fill the seat vacated by the October death of Sen. Jenny Oropeza.

Democrats have a 23-point registration advantage in the Los Angeles County district, which stretches along the coast from Marina del Rey to Redondo Beach and includes parts of Los Angeles and Long Beach.
A special primary election, which will be conducted under the state's new top-two primary rules, has been scheduled for Feb. 15. If no candidate wins more than 50 percent of the vote, a run-off will be held April 19.
