He moved west to Cunningham, Washington, in 1907, to Ontario, Oregon, in 1910, and finally to Nampa, Idaho, in 1922.

Gossett was elected to the governorship in his own right in 1944, winning the June primary over Idaho State Auditor Calvin Wright and Idaho Secretary of State George Curtis,[2] as well as the November general election over William Detweiler, the Republican nominee from Hazelton.

[3] This was the last election for a two-year term, but Gossett served less than a year; he resigned in November 1945 to let his successor, Lieutenant Governor Arnold Williams, appoint him to the United States Senate to succeed the late John Thomas.

[4][5][6] In the special election for the seat in 1946, Gossett was defeated in the Democratic primary in June by State Senator George Donart,[7] who in turn was defeated by Republican U.S. Representative Henry Dworshak in the general election in November.

[9] Following an extended illness, Gossett died at age 86 in Boise on September 20, 1974,[11] and is interred at Kohlerlawn Cemetery in Nampa.
