- The Cook Partisan Voting Index (PVI) measures how strongly a state leans toward the Republican or Democratic Party based on its voting patterns in presidential elections. The PVI is expressed as a margin (e.g., “R+25”) that shows how much more Republican (or Democratic) a state is compared to the national average. For example, “R+25” indicates that Republicans typically perform 25 percentage points better than the national average in that state.
- The PVIs for states are calculated based on the results of the U.S. presidential elections in 2016 and 2020. The table below reflects the state of Congress and governors, based on the 2024 election results.
Across the nation, U.S. citizens have different political beliefs. Some citizens lean more to the right – or Republican – with conservative values. In contrast, others lean more to the left and support the more liberal Democratic party.
While some states are pretty closely divided, there are others where most residents support one party. One way this is measured is through the Cook Partisan Voting Index, also known as the CPVI. This measures how strongly a state leans Republican or Democratic compared to the entire nation. Following each election, this index is updated to provide the most accurate results.
CPVIs are calculated by taking a look at the average Democratic or Republican share of the last two presidential elections compared to the national average. Results of the CPVI are broken down by congressional district and by state. By using this data, you can quickly determine which states are more Republican or more Democratic.
Based on the latest CPVI data, Wyoming is the most Republican state in the nation. Following behind is West Virginia, then North Dakota takes third place.
