Elections were held for the 61st United States Congress, occurring during the Fourth Party System. Oklahoma joined the union during the 61st Congress. Despite the Panic of 1907, the Republicans continued to control the presidency and both houses of Congress.

In the presidential election, the Republican former Secretary of War William Howard Taft defeated the Democratic former Representative William Jennings Bryan of Nebraska. Taft and Bryan won both of their respective parties' nominations on the first ballot. Taft easily won the election, taking most states outside the Southern United States. Bryan's loss made him the only presidential nominee of a major party to lose three general elections.

The Democrats made minor gains in the House, but the Republicans maintained a solid majority in the chamber.

In the Senate, Democrats picked up one seat, but Republicans continued to hold a commanding majority.
