The 1958 United States Senate elections were elections for the United States Senate which occurred in the middle of President Dwight D. Eisenhower's second term. As is common in midterm elections, the party in the White House lost seats, but losses this year were more than usual, perhaps due to the high unemployment of the Recession of 1958; the Eisenhower Administration's position on right-to-work issues galvanized labor unions which supported Democrats. The launch of Sputnik may also have been a factor.

The Democratic Party took 12 Republican seats and a special election seat (10 of them by defeating incumbents), and also won both Senate seats in the new state of Alaska. Senate elections in 1959 in the new state of Hawaii were split between the two parties; combined with the 1958 results, this yielded an aggregate gain of 16 seats for the Democrats for a party balance of 65-35; this is the largest swing in the history of the Senate, and is only the second time in U.S. history that 10 or more Senate seats changed hands in a midterm election (after 1946). This election featured the most incumbent Republicans defeated since Senators were first popularly elected.^{[citation needed]}

Montana[edit]

Incumbent Mike Mansfield, who was first elected to the Senate in 1952, ran for re-election. Mansfield won the Democratic primary comfortably, and moved on to the general election, where he was opposed by Lou W. Welch, a millworker and the Republican nominee. In contrast to the close campaign in 1952, Mansfield defeated Welch in a landslide and won his second term in the Senate easily.

North Dakota[edit]

Incumbent Republican, and former Non-Partisan League (NPL) Senator, William Langer, was re-elected to a fourth term, defeating North Dakota Democratic NPL Party (Dem-NPL) candidate Raymond G. Vendsel.^[7]

Only Langer filed as a Republican, and the endorsed Democratic-NPL candidate was Raymond G. Vendsel. Langer and Vendsel won the primary elections for their respective parties.

Two independent candidates, Arthur C. Townley and Custer Solem, also filed before the deadline but had minimal impact on the outcome of the election, totaling less than 3,000 votes combined. Townley was known as the creator of the National Non-Partisan League, and had previously sought North Dakota's other senate seat in 1956.
