OAKLAND, Calif. -

Jerry Brown says he's got a special opportunity to serve in his unprecedented bid for a fourth term as California governor.
   
Brown and his wife, Anne Gust Brown, voted in a firehouse near their Oakland hills home Tuesday accompanied by their dog.
   
The 76-year-old Democrat says he's "very conscious of the fact that no one has ever served California as governor for a fourth term and probably no one ever will."
   
Two Republicans are fighting to face Brown in the November general election. A conservative state lawmaker, Tim Donnelly, faces Neel Kashkari, a socially moderate investment banker making his first run for public office.
   
Without a contentious ballot measure, low turnout was expected in the state's top-two primary. Brown says it might be that people are "relatively confident" this election.
