Official portrait
100%
of itemized money from Illinois donors, in the top quarter of State Senate Republicans

100% of the itemized money from individuals in the 2026 cycle came from donors with an address in Illinois. Ranks 136th of 860, where 1st is the highest share. 5 itemized donors.

Only donors who give more than $200 are reported with an address, so this is the share of that itemized money from donors living in Illinois, ranked among State Senate Republicans. Small gifts are not counted either way. Candidates running statewide or for federal office often draw more money from out of state.

What Anderson says

Anderson claims credit less than 96% of State Senate Republicans. Credit claiming in 0% of 9 statements, against 15% for the average State Senate Republican; 342nd of 355.

An AI model reads each of Anderson’s 9 statements in the IL 2025–26 session (9 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 Senate Republicans and ranked among them.

How to read the bars

The thick bar is Anderson; the thin grey bar is the average State Senate Republicans. A longer thick bar means Anderson does this more than peers. Rank 1 is the highest rate in the group.

Extreme labels

Anderson used extreme labels in 11% of statements, 8.7 times the peer average. 1 statement; peers 1.3%.

    Who gets the labels

    Targets named alongside an extreme label, by number of statements

    No targets recorded.

    What an extreme label is

    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.

    Month by month

    Share of statements per month, the IL 2025–26 session

    No month in this window has 10 or more statements, too few to chart month by month.

    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 IL 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; 17 of them have no statements.

    Policy

    Energy is what Anderson talks about most: 100% of policy statements, 17.4 times the peer share. Peers give it 5.8%. 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 Anderson talks about. The bills Anderson sponsors and cosponsors carry the same areas, so the two can be compared.

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

    No agreement score.Needs at least 20 policy statements and 5 bills in the window.

    What agreement means, and what it doesn’t

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

    Back to topNext: Ideology

    Ideology

    Anderson sits at +0.16 on the CSIP scale, right of 0, more liberal than 78% of State Senate Republicans. Approximate range +0.14 to +0.17, which understates the uncertainty; from 58 donors and 1,254 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”.

    Approximate range +0.14 to +0.17. From 58 donors and 1,254 roll calls. Run 2026-10-25T215945. Blue is left of 0, red right of 0.

    ← More liberalMore conservative →0Anderson +0.2State Senate Republicans +0.4Illinois Senate −0.5All State Senate +0.1

    The outlined dot is Anderson, 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 Anderson’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 Anderson 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 Anderson.

    Back to topNext: Money

    Money

    Anderson reported $79.6K in the 2026 cycle, above the State Senate Republicans’ median of $46.2K. State filings report no small-donation total. 100% of itemized individual money came from Illinois.

    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

    Anderson voted with the majority of Illinois Senate Republicans on 99.5% of party-line votes and missed 4.5% of 1,502 roll calls. Illinois Senate on average: 95.3% party unity, 95.4% attendance. Across all roll calls, Anderson voted against the majority of Illinois Senate Republicans 64 times.

    1,502 roll calls Anderson could vote on in the IL 2025–26 session, compared with Illinois 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 Anderson voted with the majority of Illinois Senate Republicans. 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.

    Key votes

    Roll calls the lab flags as key

    No votes in this window met the key-vote rules.

    How key votes are chosen

    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.

    Legislation

    Anderson sponsored 146 bills in the IL 2025–26 session; 9 became law. Cosponsored 114 others. 53% of sponsored bills got out of committee (Illinois Senate average 42%; 12th of 59).

    The bills Anderson sponsored and cosponsored in the IL 2025–26 session, 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.

    How to read the blocks

    Ink blocks are bills Anderson sponsored, ochre blocks bills Anderson cosponsored; the figure above each block is the count. Most bills in any legislature never leave committee, so a short staircase is the norm.

    What this means, and what it doesn’t

    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 Anderson’s bills; the toggle shows more.

    Online

    A site that has not changed in 90 days. Anderson’s official site had 0 pages when last crawled.

    The lab crawls Anderson’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 Anderson 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 Anderson posted

    No images from Anderson’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 Anderson is most unusual among State Senate 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 …”).

    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.
