The 1904 United States House of Representatives elections coincided with the election to a full term of President Theodore Roosevelt. 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.
