Peer group: State House Republicans. Rank 1 is the highest value in the group; the thick bar is Matthiesen, the thin grey bar the peer average. The headline is the measure on which Matthiesen is most unusual among peers (Methods, §08).
Matthiesen stresses bipartisanship less than 85% of State House Republicans. Bipartisanship in 0% of 28 statements, against 1.8% for the average State House Republican; 677th of 791.
An AI model reads each of Matthiesen’s 28 statements in the MO 2025–26 session (28 posts on X) and marks the kinds of statement it contains: a personal attack, criticism of a policy, discussion of policy, bipartisanship, credit claiming, and extreme labels. A statement can carry several. Every rate is compared with the average for State House Republicans and ranked among them.

The thick bar is Matthiesen; the thin grey bar is the average State House Republicans. A longer thick bar means Matthiesen does this more than peers. Rank 1 is the highest rate in the group.
Matthiesen used no extreme labels in 28 statements. The peer average is 1.4%.
No extreme labels in this window.
Targets named alongside an extreme label, by number of statements
No targets recorded.
Calls a politician, a party or a policy “far left”, “far right”, “MAGA”, “extreme”, “radical”, “woke”, “fascist” or “communist”. The target is who or what the label was aimed at. The lists show the five most used labels and targets; the toggle shows the rest.
Share of statements per month, the MO 2025–26 session
No month in this window has 10 or more statements, too few to chart month by month.
Each row is one kind of statement; each cell is a month, shaded against that row’s own peak (darker = closer to the peak), with the peak and the latest value written at the right. The top row counts statements. The strip covers every month of the MO 2025–26 session, the same span as the rates above, including months with no statements. A month with fewer than 10 statements is hatched, not shaded: one or two posts would swing its rate to 0% or 100%. 22 months are hatched here; 13 of them have no statements.

Newest first, the MO 2025–26 session
Five statements at a time, newest first; filters apply to the statements loaded so far. Export saves the statements that match. Sources: 28 posts on X.
Environmental Protection is what Matthiesen talks about most: 33% of policy statements, 17.5 times the peer share. Peers give it 1.9%. Agreement with legislation needs at least 20 policy statements and 5 bills.
Each policy statement is tagged by the AI model with one or more of 25 policy areas from the Congressional Research Service list, so the shares say what Matthiesen talks about. The bills Matthiesen sponsors and cosponsors carry the same areas, so the two can be compared.
Share of policy statements by area, the MO 2025–26 session
| Row | Matthiesen | Peers |
|---|---|---|
| Environmental Protection | 33% | 2% |
| Immigration | 22% | 5% |
| Taxation | 22% | 8% |
| Agriculture and Food | 11% | 4% |

The thick bar is the share of Matthiesen’s policy statements in an area; the thin grey bar is the average share for State House Republicans. A statement counts once in each of its areas, so shares can add to more than 100%. The five largest areas are shown; the toggle shows the rest.
Left: share of statements by policy area. Right: share of bills. Areas in order of their share of statements; both sides run from 0 to 37%. Grey ticks are the State House Republicans averages.

No agreement score.Needs at least 20 policy statements and 5 bills in the window.
Agreement is 1 minus the distance between the two distributions (Jensen–Shannon): 1 means Matthiesen legislates on exactly the areas Matthiesen talks about, in the same proportions; 0 means no overlap. It does not say whether the bills match the positions in the statements, only the subjects. Bills Matthiesen sponsored count fully, cosponsored bills a quarter. Shown with at least 20 policy statements and 5 bills.
Matthiesen sits at +0.47 on the CSIP scale, right of 0, more conservative than 69% of State House Republicans. Approximate range +0.29 to +0.64, which understates the uncertainty; from 11 donors and no roll calls.
CSIP, the lab’s Common-Space Ideal Point, places every official, federal and state, on one left–right scale, estimated from roll-call votes, who gives money to whom, and the text of statements. Negative is left of 0, positive right of it; 0 is the centre of the scale, not a definition of “moderate”.
CSIP ideal point
Approximate range +0.29 to +0.64. From 11 donors and no roll calls. Run 2026-10-25T215945. Blue is left of 0, red right of 0.
The outlined dot is Matthiesen, coloured by its side of 0 (blue left, red right, deeper further out); the bar through it is the approximate range (±1.96 standard errors), which understates the uncertainty; the grey ticks below are the medians of Matthiesen’s groups. 0 is the centre of the scale, not “moderate” by definition.
The score summarises how an official votes, who funds them and how they talk, relative to everyone else. It does not grade positions as good or bad, and two officials with the same score can differ on any single issue. The ± range is 1.96 standard errors, which understates the uncertainty: scores whose ranges overlap may not differ at all, and even scores whose ranges do not overlap may not differ.
Every official in each group, on the CSIP scale
| Group | Officials | Median | Share left of Matthiesen |
|---|---|---|---|
| State House Republicans | 2917 | +0.4 | 69% |
| Missouri House | 149 | +0.4 | 75% |
| All State House | 5324 | +0.1 | 83% |
Every small dot is one official on the same scale, coloured by its own score (blue left of 0, red right of 0, grey at 0, deeper further out) and spread up and down only to keep dots apart; where a group is crowded the dots overlap, and darker patches mean more officials. The large outlined dot is Matthiesen in every row; the rule is each group’s median. The table under the figure gives the share of each group to the left of Matthiesen.
Matthiesen reported $9,250 in the 2026 cycle, 27% of the State House Republicans’ median of $33.7K. State filings report no small-donation total.
Campaign money from state campaign-finance filings, as aggregates only; the lab never shows an individual donor. Campaigns must report by name every person who gives them more than $200 in a cycle (“itemized”); smaller gifts are reported only as one total (“unitemized”), so donor counts, donor states, employers and occupations describe itemized donors only. State filings report no small-gift total, so these figures add up itemized contributions only.

Colleagues who most often cosponsor with Matthiesen, by number of shared bills in the MO 2025–26 session; the square shows their party.
The score is the share of sponsored bills that a committee reported out or a chamber passed, with at least 5 sponsored bills, ranked within the peer group. Members of the majority party and committee chairs move more bills, so the rank reflects position in the chamber as well as effort. Cosponsorship partners are the five colleagues who share the most of Matthiesen’s bills; the toggle shows more.

A site that has not changed in 90 days. Matthiesen’s official site had 0 pages when last crawled.
The lab crawls Matthiesen’s official and campaign websites (weekly for Congress, monthly for the states) and keeps every page’s text, so changes can be read later; it also records social accounts and describes the images Matthiesen posts with a vision model.

“Pages crawled” is the size of the site at the last crawl; “changes in 90 days” counts pages whose text differed from the previous crawl. Sites change for many routine reasons, such as new press releases, so a high count is not by itself notable.

How this page was made. Profile built Oct 28, 2026; site last built Oct 28, 2026. Every number on the page is computed from the sources listed here, by the same rules for every official; nothing is written by hand.
The headline is the measure on which Matthiesen is most unusual among State House Republicans, chosen by one rule for every official of every party. The candidates are the rate of each kind of statement and of extreme labels, party unity, attendance, the small-donor share, the in-state share and total receipts of the latest cycle, the share of sponsored bills that got out of committee, talk-to-bills agreement, and the CSIP score’s place within the party group.
The builder ranks every measure within the same peer group the page compares it with, and writes each official’s percentile: the share of the group below the value, ties counting half, so 0.5 is the median and a value shared by many never ranks first. A measure’s score is how far that percentile sits from the median (0 in the middle, 0.5 at either end), and the highest score leads if it is above 0.25, outside the middle half of the group. Scores within 0.03 of each other are a tie, broken in this order: votes against the party majority, kinds of statement, ideology, roll calls missed, small donations, in-state money, legislation, agreement, extreme labels, receipts.
A measure counts only with at least 200 statements, 100 roll calls or 5 sponsored bills behind it and a peer group of at least 10. Two things never lead: high party unity or attendance, where most members sit, and a high rate of a kind of statement backed by fewer than 10 statements. When nothing qualifies, the headline is a neutral fact instead: statements classified, or years in office. The wording always names the direction (“in the bottom 5% of …”, “votes against the majority of …”).
