§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.
Works for Democratic candidates or groups. Hart Research's history page calls the firm the Democratic pollster for the bipartisan NBC News Poll and refers to its progressive values, and Public Opinion Strategies' description of the NBC News Poll identifies Hart as that poll's Democratic pollster.2,
Of its 38 polls listed since the 2024 election, VoteHub flags 9 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
- D+0.2 (±3.2) across 12 polls of the generic ballot and 2026 races, in 3 contests.
- Without a party-aligned sponsor
- R+1.0 (±3.0) across 10 polls
- Net approval: Donald Trump
- +1.0 points (±1.2) 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 data10,
| Published as | Polls | Elections | Average miss | Relative to other polls | Typical size of miss | 538's last rating |
|---|---|---|---|---|---|---|
| Hart Research Associates/Public Opinion Strategies | 31 | 1998–2022 | D+1.5 | D+0.7 | 3.1 pts | 2.6 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.
