2018 California Proposition 7

Proposition 7 ("Prop 7") was a California ballot proposition in that state's general election on November 6, 2018. The measure passed, by a vote of about 60% Yes to 40% No.
The proposition permits the California State Legislature to change the times and dates of daylight saving time period by a two-thirds vote, all while in compliance with federal law. For the state to have such powers, Proposition 12 (1949), which established daylight saving time in California, needed to be repealed, which can only be done by the electorate.
Since Proposition 7 passed, California Assemblymember Kansen Chu has submitted Assembly Bill 7 to "eliminate the biannual clock change in California and set the state on Daylight Saving Time year-round, pending federal authorization."
Ballot Label summary.
The California Secretary of State's summary from the Official Voter Information Guide of Proposition 7 is as follows:
"CONFORMS CALIFORNIA DAYLIGHT SAVING TIME TO FEDERAL LAW. ALLOWS LEGISLATURE TO CHANGE DAYLIGHT SAVING TIME PERIOD. LEGISLATIVE STATUTE. Gives Legislature ability to change daylight saving time period by two-thirds vote, if changes are consistent with federal law. Fiscal Impact: This measure has no direct fiscal effect because changes to daylight saving time would depend on future actions by the Legislature and potentially the federal government.
Election results.
The results of the vote were 59.75% YES to 40.25% NO.
Aftermath.
Despite passing with almost 60% of the vote, the proposition only allows the legislature to change the times and dates of daylight saving time period by a two-thirds vote all while in compliance with federal law, "which never happened because the federal government failed to give approval for the California time change." In November 2019, Chu issued a news release promising to continue his efforts to get legislation passed in Washington, DC. "I share the disappointment with other Californians that we will be switching our clocks once again this November after passing Proposition 7... Unfortunately, the California State Senate Committee on Energy, Utilities and Communications did not bring AB 7 up for a vote and the bill died. While I will not be coming back as a State Assemblymember next year, I will continue my advocacy at the state and federal level to uphold Californians’ will to get rid of our outdated practice of switching the clock back and forth twice a year. I urge everyone who voted for Prop 7 to reach out to your state and federal representatives and ask them to continue my effort in the upcoming legislative session."
