Controller Recount isn't Working for John Perez

Yesterday was day three of the California State Controller election recount. While Imperial County numbers are unavailable, Kern county numbers are. They counted ballots where John Perez beat Betty Yee 1,652 to 521. That sounds like fertile ground for missed Perez votes. It wasn't. After the recount, those ballots were Perez 1,651 to 521. That's right. He lost a vote to Ashley Swearingen. Recounts usually produce a change in votes, but this one isn't working for John Perez. Either Perez needs to have the elections' boards count a lot more ballots or he needs to just call it a day and concede.
