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 119th Congress, 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%.

Newest first, the 119th Congress
Five statements at a time, newest first; filters apply to the statements loaded so far. Export saves the statements that match. Sources: 989 posts on X, 131 press releases, 44 Congressional Record speeches, 44 newsletters.
Health is what Rochester talks about most: 35% of policy statements, above the peer share. Talk and legislation agree at 0.66 on a 0–1 scale (Senate Democrats average 0.66; 24th of 45).
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 Rochester talks about. The bills Rochester sponsors and cosponsors carry the same areas, so the two can be compared.
Share of policy statements by area, the 119th Congress
| Row | Rochester | Peers |
|---|---|---|
| Health | 35% | 27% |
| Economics and Public Finance | 22% | 24% |
| Government Operations and Politics | 19% | 22% |
| Armed Forces and National Security | 14% | 21% |
| Housing and Community Development | 13% | 6% |
The thick bar is the share of Rochester’s policy statements in an area; the thin grey bar is the average share for Senate Democrats. 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 39%. Grey ticks are the Senate Democrats averages.

talk-to-bills agreement, 0 to 1
Senate Democrats average 0.66. Ranks 24th of 45.
Agreement is 1 minus the distance between the two distributions (Jensen–Shannon): 1 means Rochester legislates on exactly the areas Rochester 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 Rochester sponsored count fully, cosponsored bills a quarter. Shown with at least 20 policy statements and 5 bills.
Rochester sits at −1.11 on the CSIP scale, left of 0, more conservative than 57% of Senate Democrats. Approximate range −1.13 to −1.09, which understates the uncertainty; from 2,142 donors and 4,324 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 −1.13 to −1.09. From 2,142 donors and 4,324 roll calls. Run 2026-10-25T215945. Blue is left of 0, red right of 0.
The outlined dot is Rochester, 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 Rochester’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 Rochester |
|---|---|---|---|
| Senate Democrats | 45 | −1.1 | 56% |
| All Senate | 98 | +0.4 | 27% |
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 Rochester 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 Rochester.
Rochester raised $1.2M in the 2026 cycle, below the Senate Democrats’ median of $2.6M. 35% of individual money came in gifts of $200 or less. 21% of itemized individual money came from Delaware.
Campaign money from Federal Election Commission 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.

From 355 itemized donors. Senate Democrats’ median $2.6M.
Each square is one percent of 2026-cycle receipts, from FEC summary totals.
| Source | Amount | Share |

| Itemized individual (over $200) | $434.5K | 35.3% |

| PACs and other committees | $354.0K | 28.8% |
| Remainder not broken out in the FEC summary (transfers, loans, refunds) | $210.1K | 17.1% |
Totals say how much a campaign took in, not how it was spent, and they rise sharply when a seat is up for election; compare cycles with that in mind. The small-donor share understates small giving when a campaign itemizes gifts made through ActBlue or WinRed.

Rochester voted with the majority of Senate Democrats on 99.5% of party-line votes and missed 0.7% of 915 roll calls. Senate Democrats on average: 95.3% party unity, 97.0% attendance. Across all roll calls, Rochester voted against the majority of Senate Democrats 25 times.
915 roll calls Rochester could vote on in the 119th Congress, compared with Senate Democrats. Attendance is the share with a vote recorded. Party unity counts only party-line roll calls, where most Democrats and most Republicans voted on opposite sides, and is the share of those where Rochester voted with the majority of Senate Democrats. The count of votes against that majority covers every roll call where the majority took a side.
votes against the majority of Senate Democrats
Party unity 99.5%, Senate Democrats average 95.3%, ranks 7th of 45. 915 roll calls in the 119th Congress.
The thick bar is Rochester, the thin grey bar the Senate Democrats average. The scale runs from 80% to 100% to show the gap.
| Row | Rochester | Peers |
|---|---|---|
| Attendance | 99.3% | 97.0% |
| Party unity | 99.5% | 95.3% |
A missed roll call has many causes, from illness to campaigning, so attendance says how often, not why. A vote against the majority can be on procedure as well as substance, and many fall on roll calls where both parties split; the key votes below show the ones that decided something.

119th Congress (2025–27), loads in batches
Rochester sponsored 45 bills in the 119th Congress; none became law. Cosponsored 333 others. 8.9% of sponsored bills got out of committee (Senate Democrats average 14%; 35th of 45).
The bills Rochester sponsored and cosponsored in the 119th Congress, from the official bill records, and how far each got: introduced, referred to or acted on in committee, passed one chamber, passed both, became law. A bill counts at every stage it has reached, so the blocks only shrink to the right.

A site that changed 67 times in 90 days. Rochester’s official site had 24 pages when last crawled on Oct 18, 2026. The lab last catalogued the images Rochester posted on Oct 14, 2026.
The lab crawls Rochester’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 Rochester 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.

The headline is the measure on which Rochester is most unusual among Senate Democrats, 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 …”).
