The election was too close to call Tuesday night as both candidates hunkered down at election parties in Chula Vista watching the returns come through in a dog fight of a finish.
Assembly member Mary Salas holds a 336 vote lead with 100 percent of the precincts reporting from all three counties: San Diego, Imperial, and Riverside, according to the Secretary of State website.
"I'm humbled by the show of support that I have received from voters across the 40th Senate District," said Assembly member Salas. "This was a contentious and hard fought campaign, and I appreciate the spirited debate with my opponent. But now is the time to move on and prepare to govern."
The Juan Vargas campaign is calling the announcement "premature" citing information from the San Diego County Registrar's office that 160,000 ballots remain uncounted in San Diego alone. There is no estimate of uncounted ballots from Riverside and Imperial counties.
Vargas and his staff believe they won't know the final official count until the end of next week.
