Election date

How do we calculate my vote power?
What goes into the rating for ballot measures: Representation: how much weight one vote carries here compared with a statewide vote — the smaller the district, the more each vote counts. You have more power in ballot measures because you vote directly on the policy.
Representation: Average · 50 out of 100
This district covers a large share of its state, so each vote carries about average weight — like a vote in a statewide race. About 39,287,377 people live here.
Show the representation math
score = 50 + 50 × ln(state population ÷ this district's) ÷ ln(50,000) = 50 + 50 × ln(39,287,377 ÷ 39,287,377) ÷ ln(50,000) = 50, measured against a statewide vote in CA (grades: 66+ high, 55+ above average, 33+ average, otherwise low; a statewide race is the 50 baseline)
Average representation + a direct vote on the policy → My vote power: Above average.
Ballot Measure
Supports: Election Integrity
California would add voter ID checks and government-data citizenship reviews. In-person voters would show government-issued ID. Mail voters would write four digits from a chosen ID on the ballot envelope. State and local costs could range from tens of millions to low hundreds of millions yearly.

A YES vote means
Voters would provide government-issued ID information each election. Officials would also review citizenship data.
A NO vote means
Signature checks and current voter-roll rules would stay in place. Most voters would not show ID each election.
