Challenger Ro Khanna conceded a closely fought race to long-time South Bay Congressman Mike Honda.
Honda thanked supporters at his campaign headquarters Friday morning. He leads Khanna by a little more than 4,000 votes.
Union leaders and elected officials supported Honda while Khanna relied on the backing of Silicon Valley tech leaders.
"Today I have a message for those right wing millionaires and billionaires you cannot buy grassroots you couldn't buy it this year and you will not buy it next year," Honda said.
When Khanna spoke to reporters Friday, he conceded defeat.
At least one pundit called the race between Honda and Khanna a quote "battle for the heart and soul of Silicon Valley."
