Election day is underway for the District 1 County Supervisor. NBC 7’s Joey Safchik explains why this local special election is so important.
Tuesday is the deadline for some San Diego County voters to submit their ballots for their next supervisor.
Seven people, including four elected officials, are vying to replace former San Diego County Supervisor Nora Vargas in her District 1 seat in Tuesday's primary.

The candidates are Imperial Beach Mayor Paloma Aguirre; Chula Vista Deputy Mayor Carolina Chavez; energy consultant Elizabeth Efird; business owner and former Imperial County Supervisor Louis Fuentes; Chula Vista Mayor John McCann; San Diego City Councilwoman Vivian Moreno; and marketing firm associate Lincoln Pickard.
Vargas announced in late December that she would not serve her second term despite winning re-election in November.

"Due to personal safety and security reasons, I will not take the oath of office for a second term," she said in a statement at the time. It was unclear what the "personal safety and security reasons" were, but board meetings have become increasingly rowdy in recent years, and Vargas was away from the board several times for unspecified reasons and had dealt with health issues resulting from nodules on her vocal cords.
The elected would fill the vacant seat for the remainder of the current term ending in January 2029.
The technically non-partisan Board of Supervisors voted unanimously on Jan. 14 to hold a special election to fill the seat. If no candidate receives a majority on Tuesday, a runoff would take place July 1.
