With 100 percent of precincts reporting, San Diego City Council District 1 candidate Sherri Lightner has 54 percent of the vote, while her opponent Ray Ellis has 46 percent of the vote.
Lightner's win in the race will give the San Diego City Council a Democratic majority, though the council is technically non-partisan.
Lightner, a mechanical engineer by training, has represented District 1 on the coastal region of San Diego.
Her strong lead early in the evening gave supporters a boost of confidence.
"I’m pretty confident that she’s won that election," San Diego County Democratic Party chair Jess Durfee. "Her numbers are only going to get better.”
As the first round of results came down, and it appeared that President Barack Obama had won the presidential bid, Democrats at San Diego's election night headquarters began singing and cheering with excitement, praising candidates such as Lightner for the victories gained across the country.
