California state elections in 2018 were held on Tuesday, November 6, 2018, with the primary elections being held on June 5, 2018. Voters elected one member to the United States Senate, 53 members to the United States House of Representatives, all eight state constitutional offices, all four members to the Board of Equalization, 20 members to the California State Senate, and all 80 members to the California State Assembly, among other elected offices.
Pursuant to Proposition 14 passed in 2010, California uses a nonpartisan blanket primary. All the candidates for the same elected office, regardless of respective political party, run against each other at once during the primary. The candidates receiving the most and second-most votes in the primary election then become the contestants in the general election.

Statewide ballot propositions
June primary election
Since the passage of a law in November 2011, state primary elections may only feature propositions placed on the ballot by the state legislature.
Proposition 68 - Passed
A $4 billion bond measure to fund various parks, natural resources protection, climate adaptation, water quality and supply, and flood protection projects. Proponents argued that these projects will ensure and protect water resources, even during times of droughts. Opponents worried about adding more bonds to California's already existing debt.
Proposition 69 - Passed
A state constitution amendment that mandates that revenues generated by the Road Repair and Accountability Act of 2017 can only be used for transportation purposes. Proponents argued that this will prevent the state legislature from redirecting these funds to non-transportation programs. Opponents argued that this will not fix or build new roads, nor would it protect gas tax revenues.
Proposition 70 - Failed
A state constitution amendment that would have required that revenue from cap and trade programs be collected in a special fund starting in 2024. The state legislature would then need a two-thirds majority vote to spend this money. Proponents argued that this will ensure that the state legislature will spend these funds wisely on high priority projects. Opponents argued that this will empower anti-environmental special interest groups because a two-thirds majority vote requirement will lead to more legislative gridlock.
