    How to read the strips

    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 CA 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%. 4 months are hatched here.

    Policy

    Health is what Umberg talks about most: 17% of policy statements. Talk and legislation agree at 0.71 on a 0–1 scale (State Senate Democrats average 0.56; 6th of 228).

    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 Umberg talks about. The bills Umberg sponsors and cosponsors carry the same areas, so the two can be compared.

    How to read the bars

    The thick bar is the share of Umberg’s policy statements in an area; the thin grey bar is the average share for State 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.

    talk-to-bills agreement, 0 to 1

    State Senate Democrats average 0.56. Ranks 6th of 228.

    What agreement means, and what it doesn’t

    Agreement is 1 minus the distance between the two distributions (Jensen–Shannon): 1 means Umberg legislates on exactly the areas Umberg 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 Umberg sponsored count fully, cosponsored bills a quarter. Shown with at least 20 policy statements and 5 bills.

    Back to topNext: Ideology

    Ideology

    Umberg sits at −0.60 on the CSIP scale, left of 0, more conservative than 59% of State Senate Democrats. Approximate range −0.64 to −0.55, which understates the uncertainty; from 216 donors and 1,152 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”.

    −0.60

    CSIP ideal point

    Approximate range −0.64 to −0.55. From 216 donors and 1,152 roll calls. Run 2026-10-25T215945. Blue is left of 0, red right of 0.

    ← More liberalMore conservative →0Umberg −0.6State Senate Democrats −0.7California Senate −0.7All State Senate +0.1

    The outlined dot is Umberg, 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 Umberg’s groups. 0 is the centre of the scale, not “moderate” by definition.

    What this means, and what it doesn’t

    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.

    How to read the strips

    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 Umberg 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 Umberg.

    Money

    Umberg reported $16.4K in the 2026 cycle, 30% of the State Senate Democrats’ median of $55.5K. 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.

    Votes

    Umberg voted with the majority of California Senate Democrats on 99.1% of party-line votes and missed 2.4% of 3,673 roll calls. California Senate on average: 98.7% party unity, 93.8% attendance. Across all roll calls, Umberg voted against the majority of California Senate Democrats 7 times.

    3,673 roll calls Umberg could vote on in the CA 2025–26 session, compared with California Senate. 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 Umberg voted with the majority of California Senate Democrats. The count of votes against that majority covers every roll call where the majority took a side.

    What this means, and what it doesn’t

    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.

    Automatically: a final-passage or override vote where the measure became law, the margin was under 10%, at least 10% of either party voted against its majority, or the bill was among the 25 most mentioned in officials’ own statements. Up to 25 per window, most recent first; five are shown. Bars show yea on the left, nay on the right, per party.

    A site that changed 21 times in 90 days. Umberg’s official site had 20 pages when last crawled on Oct 1, 2026.

    The lab crawls Umberg’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 Umberg posts with a vision model.

    Websites

    How to read the counts

    “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.

    Images Umberg posted

    No images from Umberg’s posts have been described.

    Methods and sources

    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

    The headline is the measure on which Umberg is most unusual among State 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 …”).

    How the measures work

    What politicians say
    Every post, press release, newsletter and congressional floor speech is read by a language model and marked for personal attacks, policy criticism, policy discussion, bipartisanship and credit claiming. A statement can be in several. Rates are shares of statements in the window. The methods paper.
    Extreme labels
    A statement has an extreme label when it calls a politician, party or policy “far left”, “far right”, “MAGA”, “extreme”, “radical”, “woke”, “fascist” or “communist”. The target is who the label is aimed at.
    Policy areas and agreement
    Statements and bills share 25 Congressional Research Service policy areas (state bills are assigned by a language model). Agreement is 1 − Jensen–Shannon distance between the two distributions, shown with at least 20 policy statements and 5 bills.
    Ideology (CSIP)
    Common-Space Ideal Points place federal and state officials on one left–right scale, estimated jointly from roll calls, campaign contributions and the text of statements, with standard errors. Only a validated run is shown. The methods paper.
    Campaign money
    Campaigns report by name only donors who give more than $200 in a cycle; smaller gifts are reported as one total. Federal totals and the small-donor share come from the FEC’s financial summaries of each campaign committee. Donor counts, donor states, employers and occupations cover itemized donors only. State filings report no small-gift totals, so state figures are itemized only. The lab never publishes donor names.
    Votes and key votes
    Attendance, party unity and the count of votes against the majority of an official’s own party come from roll calls (Voteview for Congress, chamber records for the states). Key votes are final-passage or override votes that became law, were decided by under 10%, saw at least 10% of a party vote against its majority, or concerned one of the 25 bills most mentioned in officials’ statements.
    Peers and ranks
    Comparisons are with the same party, chamber and level (for example House Democrats); state legislators are compared within their state and chamber for votes. Every comparison names its group. Rank 1 is the highest value in the group; tied values share the average of their ranks, and the percentile is the share of the group below the value, ties counting half.
