Below are our 2025 Cook Partisan Voting Index (Cook PVI℠) scores for all 435 districts.
A Partisan Voting Index (Cook PVI) score of D+2, for example, means that in the 2020 and 2024 presidential elections, the state or district performed about two points more Democratic in terms of two-party vote share than the nation did as a whole, while a score of R+4 means the state or district performed about four points more Republican. If a state or district performed within half a point of the nation in either direction, we assign it a score of EVEN.
