Political party strength in U.S. states
Political party strength in U.S. states refers to the level of representation of the various political parties of the U.S. in each statewide elective office providing legislators to the state and to the U.S. Congress and electing the executives at the state (U.S. state governor) and national (U.S. President) level.
History[edit]

Throughout most of the 20th century, although the Republican and Democratic parties alternated in power at a national level, some states were so overwhelmingly dominated by one party that nomination was usually tantamount to election. This was especially true in the Solid South, where the Democratic Party was dominant for the better part of a century, from the end of Reconstruction in the late 1870s, through the period of Jim Crow Laws into the 1960s. Conversely, the New England states of Vermont, Maine, and New Hampshire were dominated by the Republican Party, as were some Midwestern states like Iowa and North Dakota.
However, in the 1970s and 1980s the increasingly conservative Republican Party gradually overtook the Democrats in the southeast. The Democrats' support in the formerly Solid South had been eroded during the vast cultural, political and economic upheaval that surrounded the 1960s. By the 1990s, the Republican Party had completed the transition into the southeast's dominant political party, despite typically having fewer members due to the prevalence of Republican voting generational Democrats. In New England, the opposite trend took place; the former Republican strongholds of Maine and Vermont became solidly Democratic, as did formerly Republican areas of New Jersey, New York, and Connecticut.
Currently, the majority of the overall number of seats held in the state legislatures has been switching between the two parties every few years. As of the U.S. gubernatorial elections of 2010, the Republican party holds an outright majority of approximately 440 with 3,890 seats (53% of total) compared to the Democratic party's number of 3,450 (47% of total) seats elected on a partisan ballot.[1] Of the 7,382 seats in all of the state legislatures combined, independents and third parties account for only 16 members, not counting the 49 members of the Nebraska Legislature, which is the only legislature in the nation to hold non-partisan elections to determine its members. Due to the results of the 2010 elections, Republicans took control of an additional 19 state legislative chambers, giving them majority control of both chambers in 25 states versus the Democrats' majority control of both chambers in only 16 states, with 8 states having split or inconclusive control of both chambers (not including Nebraska); previous to the 2010 elections, it was Democrats who controlled both chambers in 27 states versus the Republican party having total control in only 14 states, with eight states divided and Nebraska being nonpartisan.[2]
Current party strength[edit]
Gallup[edit]
As of December 2019, Gallup polling found that 28% of Americans identified as Democrat, 28% identified as Republican, and 41% as Independent.[3] Additionally, polling showed that 43% are either "Democrats or Democratic leaners" and 45% are either "Republicans or Republican leaners" when Independents are asked "do you lean more to the Democratic Party or the Republican Party?"[3]
In 2018, the number of competitive states dropped down to 10, the lowest number since 2008. From 2017 to 2018, New Hampshire, Nevada, and Pennsylvania moved from competitive to lean Democratic, while West Virginia, Louisiana, and Indiana moved from competitive to lean Republican, and Nebraska moved from lean Republican to competitive.[4]
As of 2018, Massachusetts was the most Democratic state, with 56% of residents identifying as Democrat, while only 27% of residents identified as Republican. Wyoming was the most Republican state, with 59% of residents identifying as Republican, and only 25% of residents identifying as Democrat.[4]

Cook Partisan Voting Index (PVI)[edit]
Another metric to measure how much a state leans towards one party or the other is the Cook Partisan Voting Index (PVI). Cook PVIs are calculated by comparing a state's average Democratic Party or Republican Party share of the two-party presidential vote in the past two presidential elections to the nation's average share of the same. PVIs for the states over time can be used to show the trends of U.S. states towards, or away from, one party or the other.[6]
Elections and voter registrations[edit]

The following table shows all the U.S. states and to what party (Democratic or Republican) their state governors belong. Also indicated is the majority party of the state legislatures' upper and lower houses as well as U.S. Senate representation. Nebraska's legislature is unicameral, i.e., it has only one legislative house and is officially non-partisan, though party affiliation still has an unofficial influence on the legislative process.
The simplest measure of the party strength in a state's voting population is the breakdown-by-party totals from its voter registration figures (figures that can easily be obtained from the websites of the Secretaries of State or the Boards of Elections of the various states). As of 2019[update], 28 states and the District of Columbia allow registered voters to indicate a party preference when registering to vote; the following 20 states (mostly in the South and the Midwest) do not provide for party preferences in voter registration: Alabama, Arkansas, Georgia, Hawaii, Illinois, Indiana, Michigan, Minnesota, Mississippi, Missouri, Montana, North Dakota, Ohio, South Carolina, Tennessee, Texas, Vermont, Virginia, Washington and Wisconsin. The partisan breakdown "demographics" provided in the following table are obtained from that state's party registration figures (from late 2014 whenever possible) where indicated.[7] Only Wyoming has a majority of registered voters identifying themselves as Republicans; two states have a majority of registered voters identifying themselves as Democrats: Maryland and Kentucky (since 2010, Louisiana, Pennsylvania and West Virginia have all seen their Democratic-majority registrations slip to just Democratic-pluralities).
For those states that do not allow for registration by party, Gallup's annual polling of voter party identification by state is the next best metric of party strength in the U.S. states. The partisan figures in the table below for the 22 states that don't register voters by party come from Gallup's 2017 polling of voter party identification by state.
