Polls from the VoteHub polling API, used under CC BY 4.0. Each result links to the pollster's or sponsor's own release. Imported once a day; a poll VoteHub later changes keeps its earlier version on record here.
§1Pollsters with polls since the 2024 election
Why this matters: The same race can look different depending on whose polls you read. These columns show, for each firm, the facts that help you weigh its numbers.

The number in brackets is how many polls each figure rests on. D+ means more Democratic than the comparison, R+ more Republican. Neither column says a firm is right or wrong: the other polls can be the ones that are off, and past elections aren't this one.
