1966 United States House of Representatives elections

Template:Short description Template:Use mdy dates Template:Infobox election The 1966 United States House of Representatives elections was an election for the United States House of Representatives on November 8, 1966, to elect members to serve in the 90th United States Congress. They occurred in the middle of President Lyndon B. Johnson's second term. As the Vietnam War continued to escalate and race riots exploded in cities across the country, Johnson's popularity had fallen, and the opposition Republican Party was able to gain a net of 47 seats from Johnson's Democratic Party, which nonetheless maintained a clear majority in the House. This was also the first election that occurred after the Voting Rights Act of 1965 became law, the first time since 1870 that a Republican won a House seat in Arkansas, and the first since 1876 that the party did so in South Carolina (after the same in a 1965 special election for the seat).<ref>Template:Cite book</ref>
