Says vs does

What this member said while seeking the office, set against how they voted once they held it. We state only whether the two records differ — never why.

No stated positions have been collected for this member yet. This comparison needs a quote with a citation — a candidate guide, a town hall transcript, a floor video — found and recorded by a person. There is no feed of things politicians said, so an empty section here means nobody has done that reading, not that the member has never contradicted themselves and not that they have.

Showing the 40 most recent of 6,895 recorded votes. Each tally links to the roll call itself, which names every member.

The tally is what the chamber recorded, not a verdict. Final passage needs a majority of the members elected, an amendment a majority of those voting, and some motions two-thirds; which rule governed a given motion is not in the record we hold.

Votes against their own party’s majority

86

Counted only where their party had a clear majority on that roll call. A tied party is not a position to diverge from.

This filing was matched, not looked up. The Legislature and the PDC share no identifier. We matched Tana Senn to PDC filer SENNT 040 because the surname, the given name, the office (State Representative) and the district (41) all agree, and because only one person fits. If that is the wrong person, tell us at corrections@washingtonindependents.org and we will unpublish this section while we check — see Corrections.

How the seat was won

How to run for this office

This is an office, not a possession. Every seat here is filled by whoever files for it and wins, and the requirements are the same for everyone.

Filing requirements and next election by seat
Seat Term Next election Filing opens
State Representative, District 41 2 years 2026 May 2026

1 form

declaration of candidacy

Filed with the Secretary of State, online or on paper. It states your name as it will appear on the ballot, the office, and that you are qualified.

1 week

the filing window, every May

Monday to Friday, closing at 4:00pm. There is no late filing: miss it and the seat is decided without you.

0

signatures, endorsements, prior offices

You must be a registered voter living in the district on the day you file. That is the entire qualification, and no party is asked about you.

C-1

only once money moves

A campaign committee and PDC reporting are required within two weeks of raising or spending anything. Raise nothing and you file nothing.

What the job is. The Legislature sits for 105 days in odd-numbered years and 60 days in even ones, and the work does not stop when the session does — committee days, constituent casework and district meetings run through the interim. Someone deciding whether to file needs that more than they need anyone’s opinion of the incumbent.

Reporting follows money, not candidacy. Registering with the Public Disclosure Commission and filing contribution reports is triggered by raising and spending, not by putting your name in. A campaign that stays under the mini-reporting threshold files a short form and nothing more.

We cannot yet tell you what filing costs. The fee is one percent of the office’s annual salary (RCW 29A.24.091 — one percent of the annual salary of the office), which makes it a specific dollar amount rather than a rule — and a page that makes you compute your own filing fee has not told you the filing fee. Legislative salaries are set by the Citizens’ Commission on Salaries for Elected Officials and we do not hold that schedule, so the figure is missing rather than estimated. A candidate who cannot pay it may file a petition of signatures instead.

This section appears on every office page on this site, contested or not, filled or vacant. Its presence is not a comment on whoever holds the seat, and we do not say whether a seat is winnable — that would be a prediction, and this page carries records.

What this page will not compute

Each of these is a number a reader might reasonably expect. None of them follow from the records we hold, so we do not publish them.

What the money bought
Where a filing is matched we show what was raised and from whom. Connecting that to how the member voted would be a causal claim from two records that were never linked, and campaign money is not the only thing that moves a vote.
A complete funding career
Cycles are shown back to 2009. A member who served before that has earlier campaigns we do not hold, so the career total is a floor rather than a lifetime figure.
Employers we cannot see
The employer field is filled in by the donor and left blank more often than not, so the bundling table shows employers we can see rather than every one that exists.
Whether a difference was a broken promise
Where a stated position and a vote differ we show both records and say only that they differ. Why is not in either one — an amendment, a procedural vote, or a bill that changed under the member all produce the same pair.
A complete set of statements
Positions are found and cited one at a time by a person. An empty or short list means nobody has done that reading, not that a member has said little.
Advertising
Meta’s ad library and PDC independent expenditures targeting this member are both public and neither is loaded.
What a divergent vote means
We can say a member voted against their party’s majority on a given roll call. Whether that was principle, a local interest, a drafting objection or a trade is not in the record, and the count is not a measure of independence.
Committee influence
Chair and ranking-member roles decide which bills get heard. The roster gives membership without role, so every seat here looks alike.
A member’s response
The design reserves space for one. We have no process yet for soliciting or publishing it, so the section is absent rather than empty.

Where this page comes from

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.

WA Legislature member roster
Name, party, district, chamber and contact details, per session served.
WA Legislature roll call service
Every recorded floor vote. Committee votes are recorded per committee rather than per member and are not included.
Party divergence
Derived, not published by the Legislature. For each roll call we take the majority position of the member’s own party and flag votes against it, counting only roll calls where that party had a clear majority.
WA Legislature legislation records
Prime sponsorship, and each bill’s outcome and hearing status. Co-sponsorship is not in the record we hold.
Public Disclosure Commission candidate filings
Contributions, expenditures, the largest reported contributors and their stated employers, for every cycle back to 2007. Matched on surname and given name plus chamber and district for a legislator, or the office won and the county it was won in for everyone else — never on name alone — and only published where one person fits. Across the record that resolves 1,938 of 13,879 officials over 3,548 cycles, with 45 refused as ambiguous; the rest say why they did not match.
Not loaded
Public statements, advertising, committee roles, and committee votes by member.
