§1About

Drafted by AI from the public sources cited. Each sentence links to its source.

The Marquette Law School Poll is a survey project of Marquette University Law School in Milwaukee that polls Wisconsin registered voters and, since 2019, U.S. adults on the Supreme Court and national issues.2,3,4 Its October 2026 methodology statement says the poll is sponsored by the Law School and directed by Prof. Charles Franklin, and that the Marquette Law School Alumni Annual Fund paid for the survey.3

§2Who it works with

Why this matters: Owners, news partners and the firms behind a poll's interviews shape what gets asked, how, and what gets published.

Part of

  • Marquette University Law School. Its methodology statements say the Law School sponsors the poll, and a 2022 Law School post says the poll released its first Wisconsin survey on January 25, 2012 and is paid for by small donations to the Annual Fund of the Law School.2,3

Fieldwork or panel by

  • SSRS. Its October 2026 Wisconsin and April 2026 national methodology statements say SSRS of Glen Mills, Pennsylvania, administered data collection, with national samples drawn from the SSRS Opinion Panel.3,4

§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. A 2022 Law School post describes the poll as an independent effort with no agenda other than learning and publishing what Wisconsin residents think, and its October 2026 methodology credits the Law School alumni Annual Fund for funding.2,3

Of its 87 polls listed since the 2024 election, VoteHub flags 0 as paid for by a Democratic-aligned sponsor and 0 by a Republican-aligned sponsor5.

§4How its numbers compare with other polls

Why this matters: A firm whose polls run steadily to one side of everyone else's is worth reading alongside others.

Each of its polls since the 2024 election is compared with other pollsters' polls of the same question whose field period ended within 14 days, each other pollster counted once5. The figure is the average gap, with a 95% margin. This compares it with other polls, not with the truth: the others can be the ones that are off.

Party margin
R+0.3 (±1.5) across 15 polls of the generic ballot and 2026 races, in 2 contests.
Net approval: Donald Trump
−1.7 points (±1.5) across 18 polls, against other polls of the same question.
Net favorability: JD Vance
−4.6 points (±1.2) across 18 polls, against other polls of the same question.
Net favorability: Donald Trump
−2.7 points (±1.3) across 15 polls, against other polls of the same question.
Net approval: Supreme Court
+7.6 points (±4.9) across 11 polls, against other polls of the same question.

D+ means its polls showed Democrats doing better than other polls did; R+, Republicans. A figure from fewer than 5 polls isn't shown.

§5Record against results

Why this matters: The one test that doesn't depend on other polls: how close a firm's final polls came to what voters did.

From FiveThirtyEight's final public data6,7: general-election polls between a Democrat and a Republican in the last three weeks before each election, compared with the certified result. FiveThirtyEight rated each name polls were published under separately. Across all 8,957 such polls, the average miss was D+0.7, so the relative figure takes out the misses every pollster shared that year.

Error is the poll's D−R margin minus the result's; D+ means it showed Democrats doing better than they did.

§7What we looked for and didn't find

  • No standing media partner found; recent methodology statements name the Law School as sponsor and no outlet.
  • No parent organization found beyond Marquette University Law School.
  • No campaign or party clients found.
  • Findings search: web searches combining the poll name with AAPOR, FiveThirtyEight, Silver Bulletin, exclusion and retraction terms found nothing that fits the finding rules; the Silver Bulletin January 2026 ratings page names no banned pollsters; FiveThirtyEight pages now redirect to ABC News and could not be read; RealClearPolitics, The New York Times, Cook Political Report, Decision Desk HQ and VoteHub policy pages were not reviewed one by one.
  • Court records: a web search limited to CourtListener and Justia found no case naming the poll; PACER and state court dockets were not searched.
