§1About
Drafted by AI from the public sources cited. Each sentence links to its source.
The Jack Citrin Center for Public Opinion Research is a UC Berkeley center for polling and public opinion research named for Jack Citrin, a longtime Berkeley political science professor; its about page says it was founded in May 2017, is housed in the Department of Political Science and is funded by donations.1 Its homepage calls it a nonpartisan multidisciplinary institution governed by an executive committee of political science professors and names David Broockman as director.2 Its site lists a series of California surveys with POLITICO, begun in 2025, that compare registered voters with policy influentials, and the August 2025 page says the influential sample was made up of POLITICO subscribers.2,
§2Who it works with

Who paid for its polls
| Sponsor | Polls | Between | Flagged party-aligned |
|---|---|---|---|

| California Constitution Center | 1 | August 12, 2025 | No |
§3Whom it works for
Why this matters: A firm that also works for one party's campaigns can still publish accurate polls, but readers deserve to know.
Says it does no work for parties or candidates. Its homepage describes the center as a nonpartisan multidisciplinary institution.2
Of its 3 polls listed since the 2024 election, VoteHub flags 0 as paid for by a Democratic-aligned sponsor and 0 by a Republican-aligned sponsor8.
§42026 record against the count
Why this matters: How close this pollster's last 2026 polls came to how people voted, measured the way FiveThirtyEight measured earlier elections.
One poll of one race between a Democrat and a Republican, with field periods ending in the 21 days before November 3, 2026, compared with each race's count. Some of those races are still being counted, so these figures use the unofficial count and will change until states certify.
- Average miss
- R+10.4
- Relative to other polls of the same races
- R+4.2
- Typical size of miss
- 10.4 pts
Error is the poll's D−R margin minus the count's, as shares of all votes in the race; D+ means it showed Democrats doing better than they did. From fewer than 5 polls, so read it as a few data points, not a pattern.

§6What we looked for and didn't find
- The March, September and October 2026 survey pages do not name who fielded the surveys or give sample sizes or field dates, and the POLITICO methodology documents could not be read because politico.com refused automated access.
- No written agreement or end date for the POLITICO series was found.
- No campaign, party or other client was found beyond the partners named on the survey pages.
- Searches found no AAPOR statement, court ruling or filing, regulator action, aggregator statement about excluding or reweighting its polls, or retraction by the firm.
- The Silver Bulletin ratings table and the VoteHub methodology pages were not read, so aggregator checks rest on searches of published text.
