The neck-and-neck race for San Jose's District 10 seat flipped by a single vote late Friday, with financial adviser Johnny Khamis taking over the long-held lead of high school sports announcer Robert Braunstein.

According to the latest update from the Santa Clara County Registrar of Voters, which has tallied all but a few hundred provisional votes, Khamis has captured 19.71 percent, or 3,482 votes, compared with Braunstein, who posted 19.70 percent, or 3,481 votes.

San Jose Planning Commissioner Edesa Bitbadal trailed in third place with 19.20 percent, or 3,392 votes -- 89 votes behind Braunstein.

Unless the remaining provisional votes alter the results significantly, the two men will face each other in a runoff for the seat in November's general election.

District 8's incumbent councilwoman, Rose Herrera, also will compete in a runoff against attorney Jimmy Nguyen.

Meanwhile, Khamis was pleased with the latest numbers, which he spied on the registrar's website early Friday night.

"I've been telling everybody that one vote matters," he said with a chuckle. "I feel good. I credit it to the hard work of my volunteers and my family. I feel blessed."

Braunstein, who is in Hawaii celebrating his 25th wedding anniversary with his wife, could not be reached for comment.

Calls to Bitbadal were not immediately returned.

Elma Rosas, a registrar spokeswoman, said about 200 provisional votes remain uncounted, and

She said the registrar's office will certify the votes of all of primary election contests by July 3, and any candidate or ballot measure committee seeking a recount must make a request within five business days of that date.

San Jose City Attorney Rick Doyle said the city charter prohibits write-in candidates in runoff elections, which occur when no candidate receives more than 50 percent of the vote.

Doyle said only the two top vote-getters in those races will be listed on the general election ballot.
