Huey, a wealthy businessman who largely self-funded his campaign, surprised political observers after he placed second in a race where coverage centered on two Democrats, Bowen and Hahn.
Huey will face long odds, however, in the July contest. The 36th District leans Democratic, and Democratic candidates combined took over 56 percent of the vote on Tuesday.
"California's 36th District is staunchly Democratic. President Obama, Governor Brown, Senators Boxer and Feinstein, and Congresswoman Harman each carried this district by significant margins," Democratic Congressional Campaign Committee Chairman Steve Israel said in a statement shortly after Bowen's concession.
"We are confident that Janice Hahn will succeed Congresswoman Harman and in Janice California's 36th District will have an outstanding advocate in Congress."
