The Cook Political Report is pleased to introduce the 2025 Cook Partisan Voting Index (Cook PVI℠) for all 435 congressional districts. First introduced in 1997, the Cook PVI measures how each state and district performs at the presidential level compared to the nation as a whole.

Democrats need to net four seats in order to win back the majority, and at the outset of the cycle that task looks herculean.

Democrats are only three seats from a House majority, but right now, the battleground of competitive races is small and fairly evenly divided between the two parties.

Our 2024 national and House vote trackers are now available. Subscribers can also access a sortable and searchable table version of the maps.
