The conservative Taft contended with major factional splits within his Republican Party. Instead of using his position as president to bridge compromise, Taft alienated the progressive wing of the party, which had championed his predecessor, Theodore Roosevelt. While conservatives controlled the largest number of elected positions for Republicans, progressive politics had been what brought many voters to the polls. The clash of these units of the Republican Party, combined with the message of unity from the Democratic Party, was enough to allow the Democrats to take control of the House, ending 16 years in opposition. This was the first time that the Socialist Party won a seat.

Protection was the ideological cement holding the Republican coalition together. High tariffs were used by Republicans to promise higher sales to business, higher wages to industrial workers, and higher demand for their crops to farmers. Progressive insurgents said it promoted monopoly. Democrats said it was a tax on the little man. It had greatest support in the Northeast, and greatest opposition in the South and West. The Midwest was the battleground.^[3] The great battle over the high Payne–Aldrich Tariff Act in 1910 ripped the Republicans apart and set up the realignment in favor of the Democrats.^[4]

In 1910, two states, with 6 seats between them, held elections early:
