§1About

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

GreatBlue Research is a Connecticut research firm; a 2021 notice from the Town of Groton describes it as a professional research firm located in Glastonbury and says it would run that town's community survey by live-caller phone and online.1 Sacred Heart University's July 2026 report of findings names Michael Vigeant as chief executive of GreatBlue Research, and a 2017 university release lists him with the same title.2,3 Sacred Heart University's August 2026 release says the Sacred Heart University/WFSB/CT Insider poll of 1,000 registered Connecticut voters, fielded July 21 to 26, 2026 by digital survey, was conducted by GreatBlue Research, and WFSB published results from the same poll.4,5

§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.

Polls regularly for

  • Sacred Heart University Institute for Public Policy and Civic Engagement (2017–now). An October 2017 Sacred Heart University release says GreatBlue Research was conducting polling on behalf of the university's Institute for Public Policy, and the university's July 2026 report says Sacred Heart University and GreatBlue Research partner to research public issues, with GreatBlue supplying research design, analysis and reporting.2,3

Led by

  • Michael Vigeant. Sacred Heart University's 2017 release and its July 2026 report both name Michael Vigeant as chief executive of GreatBlue Research.2,3

Who paid for its polls

Sponsors named on its polls, most polls first6. A party-aligned flag is VoteHub's, per poll.

§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.

Doesn’t say whom it works for. The firm's own website refused automated requests, and the university and town pages read do not say whether GreatBlue Research works for candidates or parties or name any campaign or party clients.1,2

Of its 2 polls listed since the 2024 election, VoteHub flags 0 as paid for by a Democratic-aligned sponsor and 0 by a Republican-aligned sponsor6.

§4Record 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 data7,8: 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.

ABC News closed FiveThirtyEight in March 2025; its data stops at the 2022 elections. 2026 results will be added once states certify them.

§6What we looked for and didn't find

  • The GreatBlue Research website (greatblueresearch.com) returned HTTP 403 for every page tried, so its own about, team and client pages were not read.
  • No founding year was found on a primary source; a conference speaker biography found in search gives a history, but that page could not be read (see pointers).
  • No ownership or parent organization was found.
  • WFSB and CT Insider appear with Sacred Heart University on the 2026 gubernatorial poll; whether they have a standing arrangement with GreatBlue itself, rather than with the university, was not established, and earlier Sacred Heart polls with the Hartford Courant and Hearst were seen only in news search results.
  • No fieldwork or panel vendor is named in the 2026 report beyond the digital survey method.
  • Searches found no AAPOR statement, court ruling, regulator action, aggregator statement about excluding or reweighting its polls, or retraction by the firm.
  • The DocumentCloud copy of the October 2026 Sacred Heart report returned HTTP 403.
