The Board of Supervisors will decide next week how to fill the District 1 vacancy after Nora Vargas unexpectedly announced she would not serve her second term.

Terra Lawson-Remer will continue as acting chair of the San Diego County Board of Supervisors, after a vote Tuesday to pick a new leader failed.

The San Diego County Board of Supervisors punted a vote on who will succeed Nora Vargas as chair after competing motions to elevate either Terra Lawson-Remer or Jim Desmond to the role failed in votes down partisan lines.

San Diego County Supervisors Joel Anderson and Terra Lawson-Remer were sworn into office Monday to begin their second terms representing Districts 2 and 3, respectively.

Monday was the last day in office for San Diego County Board of Supervisors Chairwoman Nora Vargas and a handful of elected officials are competing for her seat.

The county Board of Supervisors should approve a special election rather than a political appointment to fill the District 1 seat vacated by Nora Vargas, a candidate said Tuesday.

Lawson-Remer, officially vice chair, nominated herself to succeed former District 1 Supervisor Nora Vargas. With the departure of Vargas, a Democrat, the board's current make-up is two Democrats (Lawson-Remer and Montgomery Steppe) and two Republicans (Anderson and Desmond).
