§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.

Who paid for its polls

§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 HarrisX website does not say whether it works for party candidates. It says HarrisX was the researcher of record for No Labels, which it calls a moderate think tank, through the 2024 election, and that its data have been cited by both Republican and Democratic White Houses.⁴

Of its 115 polls listed since the 2024 election, VoteHub flags 0 as paid for by a Democratic-aligned sponsor and 1 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+4.7 (±0.9) across 15 polls of the generic ballot and 2026 races, in 1 contest.

Net approval: Donald Trump

+7.4 points (±1.3) across 24 polls, against other polls of the same question.

Net favorability: JD Vance

+7.5 points (±1.3) across 23 polls, against other polls of the same question.

Net favorability: Donald Trump

+7.3 points (±1.0) across 20 polls, against other polls of the same question.

Net approval: Congress

+11.7 points (±4.0) across 18 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.

§5Its polls

§6What we looked for and didn't find

• The Hill and Deseret News logos appear on its partners page without dates or descriptions, and no announcement of those arrangements was retrieved.
• The Stagwell 2025 annual report was read only in part and was not seen to name HarrisX itself; its subsidiary list was not checked.
• No fieldwork vendor or panel source was found.
• 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 could not be read, so aggregator checks rest on published text from aggregators and news searches.
