Watching the train wreck that is Nadia Lockyer’s life has been difficult. The Alameda County supervisor is now in drug-and-alcohol rehab after a bizarre incident in which she says she was assaulted by her ex-boyfriend at a Newark motel. She had been looking frail for months. And it’s come out that she took her eight-year-old son to the late-night rendezvous with her ex. Then the Chron reported last weekend, citing anonymous sources, that Lockyer’s ex has a sex video of her. Nadia Lockyer’s personal life, in short, has spiraled out of control.
