1984 United States House of Representatives elections
The 1984 United States House of Representatives elections was an election for the United States House of Representatives on November 6, 1984, to elect members to serve in the 99th United States Congress. They coincided with the re-election of President Ronald Reagan in a landslide. This victory also yielded gains for Reagan's Republican Party in the House, where they picked up a net of sixteen seats from the Democratic Party. Despite Reagan's extremely large electoral victory, the Democrats nonetheless retained a commanding majority in the House and actually gained seats in the Senate. These elections were the last until 2020 when a member of a political party other than the Democrats, Republicans, or an independent had one or more seats in the chamber. This would be the last time for eight years that the Democrats experienced a net loss of seats in the House. Overall results
