Six-year itch

The six-year itch, according to political scientists, is the pattern which takes place during a US president's sixth year in office. This year is characterized by the nation's disgruntled attitude towards the president and their political party. During this time, there is a midterm election and the incumbent President's party usually loses a significant number of seats in Congress.

Thomas Jefferson is the only two-term president in American history whose party gained seats in both houses in the sixth year of his presidency.

The term is derived from the phrase "seven-year itch", referring to a supposed pattern that relationships often sour after seven years of marriage, and the 1955 film of the same name. One of the earliest uses of the term in politics was by Republican strategist Kevin Phillips in a nationally-syndicated 1973 column which looked ahead to the 1974 midterms.[1]
