Proposition 39: Voter Identification and Citizenship Verification
November 3, 2026 · California · Statewide
How do we calculate vote impact?
Vote impact = representation (how much weight one vote carries here, the smaller the district's population, the higher the representation) + decisiveness (how likely this race is to be close, based on past results and number of candidates).
Representation: Low · 0 out of 100
This district is large for its type, so each vote is a smaller slice of the outcome. About 39,287,377 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(39,287,377 ÷ 39,287,377) ÷ ln(39,287,377 ÷ 582,397) = 0, comparing all statewide districts nationwide (grades: 66+ high, 33+ average, otherwise low)
Ballot measure: +1 step
Your vote sets the policy directly, so the rating gets a one-step boost.
Low representation + a ballot-measure boost → Average vote impact.
Ballot Measure
Election Integrity (for)
Establishes additional voter identification and citizenship verification requirements for California elections, including government-issued identification for polling-place voting or the last four digits of a government-issued identification number for vote-by-mail ballots. Requires the state to provide voter identification cards on request and elections officials to report citizenship-verification percentages.
A YES vote means
A yes vote approves adding the voter ID, vote-by-mail identification-number, voter identification card, and citizenship-verification reporting requirements described by the measure.
A NO vote means
A no vote rejects those additional voter identification and citizenship-verification requirements, leaving current voter identity and citizenship attestation rules in place.
