California Rep. Loretta Sanchez has hired the third campaign manager in her Senate race as she continues to trail state Attorney General Kamala Harris.

Sanchez hired Maria Unzueta, a former union organizer for Workers United who also worked for Hillary Clinton’s presidential primary campaign in the state, the Los Angeles Times reported.

Unzueta was preceded by Millie Herrera, who helped with the Sanchez primary campaign in June. Prior to that Sanchez’s manager was political consultant Tim Allison.

Sanchez continues to trail. Harris leads Sanchez by double digits in most polls in the two-Democrat race, the result of Harris and Sanchez finishing first and second in the state’s open primary.

Harris switched campaign managers in late 2015 after questions about campaign spending.

The two meet in their only debate Wednesday night at Cal State Los Angeles.
