Wave election analysis
- See also: Wave elections (1918-2016)
The term wave election is frequently used to describe an election cycle in which one party makes significant electoral gains. How many seats would Republicans have had to lose for the 2018 midterm election to be considered a wave election?
Ballotpedia examined the results of the 50 election cycles that occurred between 1918 and 2016—spanning from President Woodrow Wilson's (D) second midterm in 1918 to Donald Trump's (R) first presidential election in 2016. We define wave elections as the 20 percent of elections in that period resulting in the greatest seat swings against the president's party.
Applying this definition to U.S. House elections, we found that Republicans needed to lose 48 seats for 2018 to qualify as a wave election.
The chart below shows the number of seats the president's party lost in the 11 U.S. House waves from 1918 to 2016. Click here to read the full report.

Footnotes
- ↑ Denotes the party that had more seats in the U.S. House following the election.
- ↑ Lyndon Johnson's (D) first term began in November 1963 after the death of President John F. Kennedy (D), who was first elected in 1960. Before Johnson had his first midterm in 1966, he was re-elected president in 1964.
- ↑ Gerald Ford's (R) first term began in August 1974 following the resignation of President Richard Nixon (R), who was first elected in 1968 and was re-elected in 1972. Because Ford only served for two full months before facing the electorate, this election is classified as Nixon's second midterm.
