California Gov. Jerry Brown signed legislation on Wednesday that moves the state’s presidential primary election in 2020 up to March. The primary had previously been held in June, when nearly every other state had already voted, and candidates historically had not spent much time or resources in the state. “Candidates will not be able to ignore the largest, most diverse state in the nation as they seek our country’s highest office,” California Secretary of State Alex Padilla said. Prospective Democratic presidential candidates from California—namely Sen. Kamala Harris and Los Angeles Mayor Eric Garcetti—stand to benefit from the new primary date, as they would be able to win delegates from their home state earlier in the primary contest.
