- IVP compiles voter‑registration data using official records where states track party affiliation, and in states without party registration it estimates affiliations using proxy data such as primary‑vote participation. The “Major Parties” listed by IVP reflect only those parties that are officially recognized for voter registration in that state, and in states without party registration or where a party is not recognized won’t have a major party listed.
Politics in the United States is often boiled down to the standing of each state. Because of this focus, it’s no surprise that states tend to be all over the spectrum and have a long history of voting one way or another. There are two parties that dominate American politics, and even though their numbers are growing, there are few states that fall in between.
States By Political Party
To understand each state fully, we have taken a look at three types of data that represent the layering of a state’s political affiliation. The data includes
- Legislative majority paired with governor control (as seen in the table above)
- Party affiliation of each state’s governor, senate, and house
- Percentage of adults who identify as a Democrat, Republican, or neither
By looking at these different categories, the nuance of the position of each state becomes more apparent. Also, it’s good to note that political affiliation is not an accurate indicator of quality of life, cost of living, income potential, natural beauty (or lack thereof), or weather. Each state is much more than a collection of statistics regarding the political party.
Another factor to consider on this topic would be the registered voters by state.

Special Election Cases
Few states can be defined by one political standing, especially when so many run their governments and voting processes much differently. All the states below have political situations that stand farther away from the norm than their neighbors.
Alaska
A special political situation exists in Alaska where a coalition of various Alaskan leaders runs the State House. The current positions in the Alaska State House are balanced with 15 Democrats, 6 Republicans, and 2 Independents.
Maine
The Presidential Election for Maine is divided into different districts. Most of Maine voted Democratic, but the 2nd District in Maine voted Republican. Further, the Junior U.S. Senator in Maine is held by an Independent leader.
Michigan
The U.S. House of Representatives in Michigan is tied, and neither political party owns the majority. The seats are tied at seven each.
Minnesota
In Minnesota, the U.S. House of Representatives is tied, much like in Michigan. Neither the Republicans nor Democrats own the majority, with the House balanced at four seats each.
Nebraska
Similar to Maine, the Presidential Election is split between various districts in the state. In the most recent 2020 Presidential election, Nebraska mainly voted Democrat, but the 2nd District voted Republican. Additionally, Nebraska has no party voting system, so every candidate runs on the same ballot. (Montana has a similar voting system.)
Pennsylvania
Like Minnesota and Michigan, the U.S. House of Representatives is split in Pennsylvania. Currently, the House is split between nine Republicans and nine Democrats.
Vermont
In Vermont, the U.S. Junior Senator Seat is held by an Independent leader that does not align with either the Democrat or Republican Party.
