Should all voters be required to show government-issued identification to cast a ballot?
Richard Uihlein has contributed $17 million to support California Proposition 39, which would mandate that in-person voters provide government-issued identification. If passed by voters in November 2026, the constitutional amendment would also require mail-in ballots to include the last four digits of a government ID.
Why it matters
The measure could reshape election administration costs and operational requirements for state and local government. The Legislative Analyst's Office projects that implementation would cost taxpayers between tens and low hundreds of millions of dollars.
Richard Uihlein provided $17 million in total funding for Proposition 39, far exceeding the $1 million contribution from Reform California. The measure faces an uphill battle with current public polling indicating 55% opposition compared to 43% support.
The players
Richard Uihlein
An Illinois-based businessman and major political donor who serves as the founder of Uline, a shipping and packaging supply company.
Reform California
A political organization that serves as the second-largest donor to the campaign for Proposition 39.
Legislative Analyst's Office
The nonpartisan California agency tasked with providing fiscal and policy analysis to the state legislature.
The details
Proposition 39 proposes an amendment to the California state Constitution to change verification procedures. For in-person voting, individuals would be required to show government-issued ID, while mail-in voters would be mandated to write the last four digits of a government-issued ID on their ballot envelopes. These requirements shift verification duties and administrative costs onto state and local governments.
Timeline
December 2025: Uihlein made an initial $4 million donation to the measure.
August 2026: Uihlein provided a $6.5 million donation.
September 2026: Uihlein contributed an additional $6.5 million.
November 2026: California voters will decide on the ballot measure.
Market Landscape
Proposition 39 seeks to amend the California state Constitution to mandate new voter identification protocols. The measure follows broader regional trends regarding election security legislation and the ongoing debate over administrative mandates at the ballot box.
Businesses operating in California should monitor the potential fiscal impact of the measure, as its implementation could lead to increased public spending and shifts in administrative overhead. Operators should prepare for the possibility of new state-level voting requirements that may influence local public policy and government contracting budgets by late 2026.
The takeaway
The funding behind Proposition 39 highlights the significant resources being funneled into state-level ballot initiatives regarding election administration. Business leaders should monitor the PPIC California poll and the November 2026 election results to gauge the likely future shift in state election compliance rules.
