California Gov. Gavin Newsom signed a law on Monday enacting a universal vote-by-mail system in the state.

California sent vote-by-mail ballots to every registered voter in the state last year as part of its pandemic mitigation efforts, and that practice was left in place through this year as Newsom overcame an effort to recall him.

Newsom’s signature on Assembly Bill 37 will make that practice permanent by requiring the state to send ballots with prepaid return envelopes to all voters in statewide and local elections.
