SACRAMENTO, Calif. — California’s proposed voter ID rules are struggling to win majority support, with likely voters opposing Proposition 39 by nine percentage points, according to a poll released Oct. 19. The Citrin-POLITICO survey found 51% would vote against the measure, 42% would vote for it and 7% were undecided. Proposition 39 would require voters to show identification at polling places and include the final digits of an ID number on mail-in ballots. The results echo September surveys from the Berkeley Institute of Governmental Studies and the Public Policy Institute of California, which also showed the proposal trailing by similar margins. Voter ID has been a longstanding priority for President Donald Trump, making the issue politically charged in California. Supporters of Proposition 39 have sought to separate their campaign from Trump, but voters remain divided along party lines, the poll found. The available results did not specify support levels among individual parties. With opposition currently ahead and 7% of likely voters undecided, the measure faces an uphill path to majority backing. The poll’s release did not include further details on its methodology in the information available.
