The 2017 United States elections were held, in large part, on Tuesday, November 7, 2017. This off-year election featured gubernatorial elections in Virginia and New Jersey, as well as state legislative elections in both houses of the New Jersey Legislature and in the Virginia House of Delegates (the lower house of the Virginia legislature). Numerous citizen initiatives, mayoral races, and a variety of other local elections also occurred. Special elections were also held for one seat of the U.S. Senate, representing Alabama, and six seats of the U.S. House of Representatives. The Democrats picked up the governorship in New Jersey and the Alabama Senate seat that was up for a special election. The governorship in Virginia and the six House seats that were up for special elections did not change party hands.

Analysts such as Harry Enten of FiveThirtyEight and Chris Cillizza of CNN interpreted the 2017 election results overall as demonstrating a move toward the Democratic Party. With the Democrats picking up the Senate seat in Alabama, it reduced the Republicans' majority in the Senate to 51–49. The analysts also noted that although none of five House seats held by a Republican switched to the other party in the 2017 special elections, in each race the Democrat received a higher percentage of votes than in recent elections for the same seat. Furthermore, Democrats made large gains in the Virginia House of Delegates, and picked up 42 seats in state legislatures.[1][2]

Federal elections

The following special elections were held to replace Senators or Representatives who resigned in the 115th U.S. Congress:


House of Representatives

State and territorial elections

Two states held gubernatorial elections in 2017:


Main article: 2017 United States state legislative elections

The two states that held gubernatorial elections also held legislative elections:

Democrats also won control of the Washington Senate through a November special election. As part of a federal court ruling that invalidated its state legislative districts, the North Carolina General Assembly was ordered to hold special elections in the fall of 2017 with updated district lines. However, the US Supreme Court has put a hold on the 2017 election until it rules on the matter.[15][16]


Two states held supreme court elections in 2017:

Puerto Rican status referendum

Main article: 2017 Puerto Rican status referendum

A referendum regarding the political status of Puerto Rico was held on June 11. Puerto Rican voters were asked whether they prefer statehood, independence/free association, or maintain the current U.S. territorial status. This was the fifth such plebiscite overall, and the first one since 2012.[17] Because there were almost 500,000 blank ballots in that 2012 referendum, creating confusion as to the voters' true desire, Congress decided to ignore that vote and then subsequently allocated funds for holding this 2017 one.[18][19] 97% of the voters chose statehood in the referendum, though turnout was only at 23%.[20]

Constitutional convention of New York

Main article: 2017 New York Proposition 1

Under the provisions of the New York Constitution, every twenty years the state is required to place before the voters a proposal to hold a constitutional convention to be held the following year, with any suggested amendments being voted on in the year after that. Therefore, in November 2017 a proposal was placed on the ballot for a 2018 convention, with any amendments to be voted on in 2019. On this vote, over 80% voted against a constitutional convention.

Mayoral elections

Various elections were held for officeholders in numerous cities, counties, school boards, special districts and others around the country. Below is a list of the mayoral elections held in the main cities of the United States:


Fifteen candidates who were members of the Democratic Socialists of America were elected to office in thirteen states, most notably Lee J. Carter in the Virginia House of Delegates, thus adding to the twenty members already holding elected office nationwide.[47]
