Cubas, the only woman in the field, faced African American politicos Curren Price, Mike Davis, and David Roberts as well as Asian American and LAPD deputy chief Terry Hara.
With 100 percent of precincts reporting, neither Price nor Cubas got more than 50 percent of the vote, so the contest goes to a runoff.
Price, a current state senator, is the latest job-hopping legislator angling to win the far higher-paying $178,789 Los Angeles City Council job and creating what is being dubbed as "Sacramento South."
Cubas is the underdog, with Price receiving major financial backing by labor unions.
Like Council District 13, CD 9 is a highly coveted City Council seat, which covers part of downtown Los Angeles. The council member will have tight connections to deep-pocketed downtown business interests, helping one's political future.
Current District 9 Councilwoman Jan Perry, who will be termed out, ran for mayor.
