1998_United_States_elections
The 1998 United States elections were held on November 3, 1998, in the middle of Democratic President Bill Clinton's second term and during impeachment proceedings against the president as a result of the Clinton–Lewinsky scandal. Though Republicans retained control of both chambers of Congress, the elections were unusual because this is the first midterm since 1934 that the president's party gained seats in the House of Representatives.
Several Senate seats changed hands, but neither party made a net gain. In the House of Representatives, Democrats picked up five seats, marking the first time since the 1934 elections in which the incumbent president's party did not suffer losses in either house of congress. This also occurred in 2002. This is the most recent midterm election in which neither chamber of Congress changed partisan control.
The disruption of the six-year itch is attributed to wide opposition to the impeachment investigations against Clinton and his high popularity numbers.
