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.

Recall campaigns in the East Bay to oust Oakland Mayor Sheng Thao and Alameda County District Attorney Pamela Price appear to have won by wide margins in unofficial results updated Wednesday morning.
