It was my goal to make Oakland safer, cleaner, and more vibrant,” Thao said in a statement. “And I am proud of what we accomplished together.”

The effort to recall Oakland Mayor Sheng Thao is now in the hands of voters, less than two years since she assumed office.

The signature gathering required to bring Thao’s recall before voters was bankrolled by a single Piedmont resident, Farallon Capital hedge-fund manager Philip Dreyfuss, who poured at least $1.9 million into the Alameda County elections this past year.
