The 1904 United States House of Representatives elections were held for the most part on November 8, 1904, with Oregon, Maine, and Vermont holding theirs early in either June or September. They coincided with the election to a full term of President Theodore Roosevelt. Elections were held for 386 seats of the United States House of Representatives, representing 45 states, to serve in the 59th United States Congress. Roosevelt's popularity swept many Republican house candidates into office, cementing their majority over the opposition Democratic Party. Because Roosevelt came from a liberal wing of the Republican Party, his ideology was prevalent among freshman representatives. Progressive Republicanism mobilized a new base of support and proved to be especially popular among the Protestant middle-class workers who held jobs in business or in the front offices of industrial facilities.
