Since Idaho became a U.S. state in 1890, it has sent congressional delegations to the United States Senate and United States House of Representatives, beginning with the 51st United States Congress. Prior to 1890, Idaho sent non-voting delegates to the House of Representatives from 1864 to 1889. Each state elects two senators to serve for six years in general elections, with their re-election staggered. Prior to the ratification of the Seventeenth Amendment in 1913, senators were elected by the Idaho Legislature. Each state elects a varying number of, but at least one, member of the House, depending on population, to two-year terms. Idaho has sent two members to the House in each congressional delegation since the 1910 United States Census.
The 1998 United States Senate elections were held on November 3, 1998, with the 34 seats of Class 3 contested in regular elections. This was seen as an even contest between the Republican Party and Democratic Party. While the Democrats had to defend more seats up for election, Republican attacks on the morality of President Bill Clinton failed to connect with voters and anticipated Republican gains did not materialize. The Republicans picked open seats up in Ohio and Kentucky and narrowly defeated Democratic incumbent Carol Moseley Braun, but these were cancelled out by the Democrats' gain of an open seat in Indiana and defeats of Republican Senators Al D'Amato and Lauch Faircloth. The balance of the Senate remained unchanged at 55–45 in favor of the Republicans.

Bush's term, and as with most other midterm elections, the party not holding the presidency gained seats in Congress. This was the first time since 1980 that any party successfully defended all their own seats, and the first time Democrats did so since 1958.

The 1980 United States Senate elections were held on November 4, coinciding with Ronald Reagan's victory in the presidential election. The 34 Senate seats of Class 3 were contested in regular elections. Reagan's large margin of victory over incumbent Jimmy Carter gave a huge boost to Republican Senate candidates, allowing them to flip 12 Democratic seats and win control of the chamber for the first time since the end of the 83rd Congress in January 1955. This was the first time since 1966 that any party successfully defended all their own seats.
The 1976 United States Senate elections was an election for the United States Senate. Held on November 2, the 33 seats of Class 1 were contested in regular elections.

Each party flipped seven Senate seats, although, one of the seats flipped by Democrats was previously held by a Conservative.
The 1972 United States Senate elections were held on November 7, with the 33 seats of Class 2 contested in regular elections.

The 32 Senate seats of Class 2 were contested in regular elections, and six special elections were held to fill vacancies. Eisenhower's Republican party lost a net of two seats to the Democratic opposition. This small change was just enough to give Democrats control of the chamber with the help of the Independent who at the start of this Congress in January 1955 agreed to caucus with them; he later officially joined the party in April 1955.
