The Cook Partisan Voting Index, often abbreviated as PVI, is a measurement of how strongly a Congressional District or State leans Democrat or Republican, compared to the nation as a whole using Presidential elections as the baseline.
The index is updated after each Presidential election cycle. For PVI by State, click here.
The Following PVIs that are listed by Congressional District use the 2018 election winners with the 2012 and 2016 Presidential elections as a baseline (e.g., the 2018 winner of Alabama’s 1st Congressional District is a Republican in a district which voted for the last two Presidential candidates Mitt Romney and Donald Trump by an average of 15 percentage points over the Republican national average of 47%).
