Sen. Bernie Sanders, front-runner for the Democratic presidential nomination, announced Wednesday he will return to California on Sunday for a San Jose rally ahead of the Super Tuesday primary elections as a new poll showed him leading a crowded field of rivals in the state.

His campaign said it will have staff at the rally to collect vote-by-mail ballots and turn them in to county registrars — San Jose is in Santa Clara County, which is switching to mailed ballots this year under the state’s 2016 Voter’s Choice Act. The ballots can be returned by mail, postmarked through Election Day, or dropped off at county election offices.
