Residents of north San Jose's Berryessa district have until 8 tonight to cast their vote for a new City Council member.

Manh Nguyen and Tim Orozco are competing in a special runoff for the District 4 seat, which opened up when Kansen Chu was elected to the Assembly. The seat has been filled in the interim by Margie Matthews, who was appointed by Mayor Sam Liccardo until voters picked someone to serve the remainder of the term.

Election officials expect a low turnout, an estimated 30 percent of the district's 41,000 registered voters. Only 25 percent of voters made it out for the April 7 election thinned the race from a field of 10 candidates to the two competing in today's runoff.

Santa Clara County's Registrar of Voters has staffed 26 polling stations, which close at 8pm. Voters who received mail-in ballots can drop them off in person at any polling place, one of several other drop-off sites or at the ROV office—as long as it gets there before the polls close.

Here's a list of drop-off locations and hours.

Voters can also look up their designated polling places online, by using the ROV's free SCCVOTE mobile app or calling the ROV office at 866-430-8683.

Live results will be posted after 8pm and updated in 45-minute intervals until all ballots are counted. Meanwhile, voters can follow the ROV on Facebook and Twitter.

Nguyen, 62, runs a Vietnamese media company and has claimed support from business groups, including the San Jose Silicon Valley Chamber of Commerce and fiscally conservative leaders, including Liccardo, Vice Mayor Rose Herrera and former Mayor Chuck Reed. Here's a link to his campaign website.

Orozco, 46, enjoys support from the South Bay Labor Council and labor-backed leaders like his boss, state Sen. Bob Wieckowski, and council members Ash Kalra, Don Rocha and Raul Peralez. Click here to visit his campaign website.
