2014 United States elections

Elections were held in the United States on November 4, 2014, in the middle of Democratic President Barack Obama's second term. A typical six-year itch midterm election suffered by most second-term presidents, this election saw the Republican Party expanding their majority in the House of Representatives and winning control of the Senate, while furthering their gains in the governorships and state legislatures. Because of these Republican gains, the election was commonly cited as a "red wave" election.

Republicans won a net gain of nine Senate seats, the largest Senate gain for either party since the 1980 United States elections. In the House, Republicans won a net gain of thirteen seats, giving them their largest majority since the 1928 elections. In state elections, Republicans won a net gain of two gubernatorial seats and flipped control of ten legislative chambers. Various other state, territorial, and local elections and referendums were held throughout the year.

With total spending reaching $3.7 billion, the midterm election, at the time, was the most expensive in history, being surpassed by the 2018 midterm election four years later. The 2014 election also saw the lowest turnout since 1942, with just 36.4% of eligible voters voting. Coupled with the 2010 midterms earlier in the Obama administration, this election marked the first time since the Reagan Administration that a two-term president's party suffered net losses in both houses of Congress in both midterm elections.
