| Sponsor | Polls | Between | Flagged party-aligned |
|---|---|---|---|
| Carolina Journal | 9 | August 12, 2025 – October 20, 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.
Works for Republican candidates or groups. Harper's pages do not describe its party orientation in words; the party committee and campaigns it names as clients (the NRCC, Trump 2020, Vivek 2024 and Glenn Youngkin's Virginia campaign) are all Republican, and it names no Democratic committee or campaign. This rests on the clients it names.1,
- National Republican Congressional Committee. Harper's homepage shows the NRCC among the logos of committees, campaigns and causes it says trust the firm, and its about page mentions McCleary's earlier work at the NRCC.1,
2 - Donald J. Trump 2020 reelection campaign (2020–now). Harper's homepage shows a Trump 2020 logo among its client logos, and its about page says McCleary was a pollster for President Donald J. Trump's reelection.1,
2 - Vivek 2024 (2024–now). Harper's homepage shows a Vivek 2024 logo among its client logos.1
- Glenn Youngkin campaign for governor of Virginia. Harper's about page mentions work on Glenn Youngkin's campaign in Virginia.2
Of its 9 polls listed since the 2024 election, VoteHub flags 0 as paid for by a Democratic-aligned sponsor and 0 by a Republican-aligned sponsor4.

§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 once4. 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+2.2 (±4.0) across 5 polls of the generic ballot and 2026 races, in 1 contest.
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 |
|---|---|---|---|---|---|---|
| Harper Polling | 10 | 2013–2020 | D+1.7 | R+0.7 | 1.8 pts | Not graded (inactive) · 0% partisan work |
| Harper Polling/Clarity Campaign Labs | 1 | 2019 | D+7.0 | D+3.7 | 7.0 pts | Not graded (inactive) |
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.
One poll of one race 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+9.6
- Relative to other polls of the same races
- R+1.7
- Typical size of miss
- 9.6 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
- Its own site gives two founding years: the about page says 2013 and the footer reads 2012 to 2026.
- The year Harper left Cygnal was not stated on the pages read.
- No start date was found for the Carolina Journal arrangement; the Carolina Journal poll pages read do not name the firm conducting the poll, so the relationship rests on Harper's own news page.
- No fieldwork or panel vendors were named; its pages describe methods only in general terms.
