§1About
Drafted by AI from the public sources cited. Each sentence links to its source.
The Siena Research Institute (SRI), formerly the Siena College Research Institute, says it was founded in 1980 at Siena University in New York's Capital District and conducts regional, statewide and national surveys.2,
§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
News partners
- The New York Times (2013–now). SRI's January 2026 announcement says it began the partnership that produces the NYT/Siena Poll in 2013; a 2023 Siena University article quotes an SRI staff member dating it to early 2012.2,
6 - Newsday. SRI's website lists a section headed as a partnership with Newsday.7

Who paid for its polls
| Sponsor | Polls | Between | Flagged party-aligned |
|---|---|---|---|
| Portland Press Herald | 5 | June 26, 2026 – September 22, 2026 | No |
| Texas A&M University Bush School of Government & Public Service | 4 | June 4, 2026 – July 30, 2026 | No |
| The Philadelphia Inquirer | 3 | August 21, 2026 – September 22, 2026 | No |

| WPTZ | 1 | October 6, 2026 | 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 Policy of Non-partisanship calls SRI a non-partisan organization that does not support or oppose candidates or take a stand for or against a political party.3
Of its 69 polls listed since the 2024 election, VoteHub flags 0 as paid for by a Democratic-aligned sponsor and 0 by a Republican-aligned sponsor8.
§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 once8. 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
- D+1.3 (±1.5) across 41 polls of the generic ballot and 2026 races, in 18 contests.
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 data9,
| Published as | Polls | Elections | Average miss | Relative to other polls | Typical size of miss | 538's last rating |
|---|---|---|---|---|---|---|
| The New York Times/Siena College | 92 | 2016–2022 | D+1.3 | D+0.7 | 4.1 pts | 3.0 of 3 |
| Siena College | 57 | 2002–2022 | R+3.2 | D+0.3 | 5.7 pts | 2.7 of 3 |
ABC News closed FiveThirtyEight in March 2025; its data stops at the 2022 elections. 2026 results will be added once states certify them.
§62026 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.
4 polls of 4 races 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+3.2
- Relative to other polls of the same races
- D+2.7
- Typical size of miss
- 3.3 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.

§8What we looked for and didn't find
- Sources disagree on when the New York Times partnership began: SRI's 2026 announcement says 2013, while a 2023 Siena University article quotes a staff member saying early 2012.
- Neither SRI nor ReconMR says who owns what after the January 2026 integration.
- The October 2026 ReconMR Texas Poll release read does not mention Siena, so the ReconMR/Siena University byline on Texas polls was not traced to a statement of each party's role.
- Albany Times Union, WAMC-FM, WPTZ, the Maine Trust for Local News, the Portland Press Herald, The Philadelphia Inquirer and the Texas A&M Bush School appear as sponsors on its polls in our data; no page describing a standing arrangement with any of them was read.
- No start date was found for the Newsday partnership.
- No call centers or panel vendors used for NYT/Siena polls were confirmed from a primary page.
- Searches found no AAPOR statement, court ruling or filing, regulator action, aggregator statement about excluding or reweighting its polls, or retraction by the firm.
