“Blue states” are states that have a more liberal population and culture, as opposed to the conservative “red states.” While there are many more red states than blue states, the blue states tend to have much higher populations, so they have higher numbers in indexes like the electoral college and the number of congressional representatives.
There are also neutral states, usually referred to as “swing states” because these states could go either Democratic or Republican in an election. Candidates typically do most of their campaigning in the swing states, including Pennsylvania, Virginia, Wisconsin, Michigan, Iowa, Minnesota, Nebraska, Colorado, Nevada, and Florida.
The most liberal state in the country is Massachusetts, where the equally progressive city of Boston is located. Next is Hawaii, followed by Rhode Island, California, New York, Vermont, Maryland, New Jersey, Connecticut, and Oregon. This index of how liberal a state is is based on how many liberals there are compared to conservatives.
Just like some states can be more liberal than others, some cities are more liberal than others. These cities tend to have high minority populations and public expressions of LGBTQ+ acceptance. The most liberal city is San Francisco, California, followed by Washington, DC; Seattle, Washington; Oakland, California; Boston, Massachusetts; Minneapolis, Minnesota; Detroit, Michigan; New York City, New York; Buffalo, New York; and Baltimore, Maryland. Notice that all of these cities are in blue states.
States can change from liberal to conservative over time due to factors like immigration, empowerment of minority groups (which tend to support liberal policies over conservative ones), and taxation. New York, for example, used to be highly conservative but is now much more progressive.
Below are the ten most liberal states in the United States. The data is based on “most conservative” rankings by the Center for Legislative Accountability.

Massachusetts is also the home state of well-known politicians such as Elizabeth Warren, Michael Dukakis, Jill Stein, and the Kennedys. That state also has many urban areas and a highly educated population – two factors that strongly contribute to a liberal environment.
Hawaii is the second-most liberal state in the United States. 28% of voters in Hawaii identify as liberal, and 22% identify as conservative, giving Hawaii a liberal advantage of 6 points, the second-highest in the country. Moderates are the largest group in Hawaii, with 45% of voters identifying as moderate, which is also the largest percentage of any state in the country.

The smallest state in the country is also the third-most liberal. Rhode Island has 25% of residents who identify as liberal, compared to 29% who identify as conservative, and 40% who identify as moderate. Rhode Island has only voted for a Republican presidential candidate twice since 1960.
California is the fourth-most liberal state in the United States. 29% of voters identify as liberal, and 29% identify as conservative, giving California a liberal advantage of zero points. 36% of voters in California identify as moderate. As the state with the most electoral votes, California’s vote is a big deal in elections. In the 2016 presidential election, 61.5% of voters voted Democratic, a 30% lead over the Republican vote.
New York is the fifth-most liberal state in the U.S. 30% of voters identify as liberal in New York versus 27% who identify as conservative, giving New York a 3-point liberal advantage. New York is geographically split, a majority of upstate areas vote conservative, and the larger metro areas vote liberal. In the 2016 presidential election, 59% of voters voted Democratic.
Vermont is the sixth-most liberal state in the country, with 32% of voters identifying as liberal. With 28% of voters identifying as conservative, Vermont has a liberal advantage of 4 points, the third-highest country. 56.3% of Vermont voters voted Democratic in the 2016 election, while 30.3% voted Republican.

Maryland legalized gay marriage, pushed for major gun restrictions, and imposed tax increases, among other progressive policies.
Although New Jersey is another state with a negative liberal advantage (-2 points), many of the state’s moderate voters tend to vote for more progressive social policies. As a result, New Jersey has not voted for a Republican presidential candidate since 1988.
Similar to New Jersey, although there are 27% of residents who identify as liberal and 30% who identify as conservative, many of the 38% of self-identified moderates lean more liberal than conservative. The state attracts many of the same highly-educated citizens as neighboring Massachusetts.
