A new Public Policy Institute of California survey finds that a majority of likely voters support Proposition 50, a November ballot measure that would temporarily change how the state draws congressional district maps — and that interest in the outcome is at record levels.

According to the survey released at 8 p.m. Tuesday, 56% of likely voters plan to vote “yes” on Prop. 50, while 43% say “no.” Support is highest among Democrats (84%) and independents (55%), but 89% of Republicans oppose it. Regional divides are sharp: 69% of voters in the San Francisco Bay Area back the measure compared with 44% in the Central Valley.

Nearly 7 in 10 likely voters (68%) said the outcome is “very important” — the highest level of interest PPIC has recorded in more than 20 years.

“We are seeing a record level of interest in Proposition 50, maybe because voters are able to express their views about the president, Congress, governor, and state legislature with a single vote,” said Mark Baldassare, PPIC Statewide Survey director and Miller Chair in Public Policy.

Trump vs. Newsom

“Of those who would vote yes on Proposition 50, 95 percent disapprove of President Trump and 86 percent approve of Governor Newsom.”

Despite the new proposal, 72% of voters still say the state’s existing citizens’ redistricting commission — established by a 2010 voter initiative — has been “mostly a good thing.”

The survey also found low approval ratings for President Donald Trump (33%) and Congress (17%), while Gov. Newsom maintains majority approval at 55%. Californians cited political extremism and threats to democracy as the nation’s biggest problem, and the cost of living as the top issue facing the state.
