Former Assembly Speaker John A. Pérez has filed paperwork seeking a partial recount in the close race for state controller.

The Democrat from Los Angeles trails Board of Equalization member Betty Yee, also a Democrat, by just 481 votes for second place in the contest.

Fresno Mayor Ashley Swearengin, a Republican, finished first.

The request will be expensive and potentially time-consuming -- it's the largest in the state's recent history.

Pérez is looking for a recount of votes in fifteen counties. A complete hand recount in LA County could cost $1 million. He'd have to foot the bill.
