Lyndon Johnson Democratic Lyndon Johnson Democratic 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 mid-term elections, the party in the White House lost seats, but losses this year were heavy due to the Recession of 1958, the Eisenhower Administration's position on right-to-work issues that galvanized labor unions which supported Democrats, and the launch of Sputnik.

Holland had played a role in recruiting George A. Smathers to run against the liberal Pepper in that election.

[5] William E. Jenner Republican Vance Hartke Democratic Incumbent Republican William E. Jenner did not seek a second full term in office and was replaced by Democrat Vance Hartke, the mayor of Evansville.

A plan was proposed whereby Handley would resign the governorship, his lieutenant would appoint him senator, and he would finish the term and run as an incumbent.

Hartke accused Handley of raising taxes, breaking of his campaign promise, his reluctance in supporting right-to-work, and rising state unemployment.

Democrat Edmund Muskie defeated one-term Republican incumbent, Frederick G. Payne by a wide margin, 61–39%.

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.

Republican Roman Hruska had won a 1954 special election and ran for a full term.

Morrison would be elected Governor of Nebraska in 1960 and serve there for six years from 1961 to 1967, and was re-elected twice while running unsuccessfully for U.S. senator.

He received support from Eisenhower cabinet secretaries Fred Seaton and Ezra Taft Benson.

Benson, one of the Twelve Apostles of the Church of Jesus Christ of Latter-Day Saints, was especially influential among Nevada's large Mormon population.

Late in the campaign, Malone published full-page ads touting his effort to save Nevada from a federal gambling tax.

[18] Cannon focused his attacks on Malone's absentee record in the Senate and his reputation on Capitol Hill as an unpopular extremist.

[18] Cannon won the election by a safe margin owing to his overwhelming support in his native Clark County, which contained 47 percent of the state's registered voters.

Republican Representative Kenneth Keating defeated Democrat Frank Hogan to succeed Ives.

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.

The Republican nominee, Hugh Scott, defeated the term-limited Democratic Governor of Pennsylvania George M. Leader for the vacant seat.

John D. Hoblitzell Jr. Republican Jennings Randolph Democratic Incumbent Democrat Matthew M. Neely died of cancer January 8, 1958, and Republican John D. Hoblitzell Jr. was appointed January 25, 1958, to continue the term, pending a special election.
