Independent spending on this measure is not in the record we hold. Money spent for or against a measure by filers who are not its committees is reported on the C-6 and names the measure in free text; the join from that text to this page is not built. The totals above are committee money only. When independent spending is added it will be kept in a ledger of its own, both sides in full, and neither side will ever be subtracted from the other.

The case for and the case against

The statewide voters’ pamphlet carries a statement for and a statement against every certified measure, written by committees the state appoints and mailed to every household.

The pamphlet statements for this measure are not reproduced here. The Secretary of State publishes the statewide pamphlet on a site that blocks automated retrieval, and we do not work around bot detection. Showing one side without the other would be worse than showing neither, so neither is shown. The statements are in the printed pamphlet and on the state’s site.

What this page will not compute

A measure before the vote is where a prediction is expected. Each of these is a prediction, or an estimate dressed as a fact.

No forecast.: Whether this measure will pass is a prediction. The money on each side is printed; what it will buy is not known to anyone.
No net money.: Money for and money against are two facts. Subtracting one from the other manufactures a third that nobody reported.
No cost per person.: The fiscal impact statement is an estimate by the Office of Financial Management. Dividing it by the population would be arithmetic on an estimate, presented as a fact about the reader.
No paraphrase of the ballot title.: The certified title is the state’s wording and we do not hold it. Our summary is labelled as ours; it is not the ballot.
No connected-records section.: A measure before the ballot is not yet a node in the entity graph. The committees funding it are, and their pages carry their edges.

How this page is built

Every figure above is read from a primary source and rebuilt on a schedule. Nothing here is modelled or inferred; where a source is silent the page says so rather than filling the gap.

The measure: the Secretary of State’s VoteWA filing list: number, subject, sponsor, dates and status copied as published. The certified ballot title and full text are on the state’s site and are not reproduced.
Money: PDC committee registrations (C-1) that declare this ballot number, joined on the ballot number a committee declared on its C-1, reduced to its three-digit core; a bare number counts only for a committee whose jurisdiction is the State of Washington. Each committee’s figure is its C-3 contribution total; a committee backing several measures appears on each with its whole total and says so.
Never netted: for and against are two figures everywhere on this page.
After the vote: this page is in the ballot-measure template’s vocabulary so the certified result can take over the same URL without a redesign.
