Corrections
Corrections log
Every material correction to a published number or claim, newest first: the date, the page, what it said and what it says now. Corrections are made in the underlying data, so they reach every chart, table and the API.
| Date | Page | Was | Now | Why |
|---|---|---|---|---|
| /2026/generic-ballot/ | Final average Democrats +8.1, from 152 polls | Democrats +8.0, from 119 polls | Polls released for several populations (likely voters, registered voters, adults) counted once each; one population per poll is now used, likely voters first, and polls listed twice are counted once. See the methodology. | |
| /approval/trump/ | 53 polls weighted | 49 polls weighted; the average did not change | Same de-duplication: four polls had been listed twice under different spellings. | |
| /2028/republican-primary/ | Vance 39.7%, Rubio 19.9%, Trump Jr. 11.9% | Vance 39.8%, Rubio 19.7%, Trump Jr. 11.7% | Same de-duplication. The home page also showed Donald Trump Jr. as "Jr."; it now shows "Trump Jr." | |
| /2028/democratic-primary/ | Harris 24.1%, Buttigieg 11.1%, Ocasio-Cortez 9.6% | Harris 24.2%, Buttigieg 11.0%, Ocasio-Cortez 9.5% | Same de-duplication. | |
| /2028/president/vance-vs-newsom/ | The July 1–4 Zogby Analytics poll listed twice (as Zogby and Zogby Analytics) | Listed once; the average did not change | Spelling variants of one pollster are now merged. | |
| /markets/ | Robert F. Kennedy Jr. 49.0% for the Republican nomination (Polymarket) | Not shown | The price had not moved in days, a sign of a closed or untraded contract; such prices are now skipped and flagged. | |
| /markets/ | A Kalshi column built from press quotes of March–October 2026, under a "latest snapshot Nov 3" label | Removed; Kalshi is linked instead | The quotes were not current and Kalshi's terms for republishing prices are unclear. | |
| /markets/ | JD Vance and J.D. Vance as two separate rows | One row per candidate | Candidate names are normalised across platforms. | |
| /pollsters/ | "The first independent pollster rating built since FiveThirtyEight stopped publishing"; "a typical poll misses by about 5 points" | Claim removed; typical error 5.8 points, the figure used on every pollster page | Other independent ratings exist, and the two pages quoted different figures. | |
| /2028/calendar/ | "Iowa/New Hampshire/South Carolina/Nevada traditionally lead", no dates | The DNC's approved early window (South Carolina first, January 22, 2028) with sources; Republican dates marked tentative | The DNC approved its 2028 calendar on August 15, 2026. | |
| All poll and average pages | Titles said "Polls Today" with the build date even when the latest poll was weeks old | Titles carry the latest poll's date, and "Today" only when a poll ended in the last 7 days |
