In 1946, Vermont political observers expected
Leonard F. Wing, the commander of the 43rd Division during the war, to run for governor. The unanswered question was whether incumbent governor
Mortimer R. Proctor would run again or would defer to Wing for the Republican nomination, tantamount to election in Vermont. Wing died in December 1945, soon after returning home from the war. Without Wing in the race, Gibson was free to announce his candidacy. Proctor decided to run for reelection, creating a rare Republican primary contest. Gibson, an internationalist and a progressive, argued against the Republican status quo. Making the case against unwritten party policies including the
Mountain Rule and the limitation of Governors to two years in office, Gibson appealed to war veterans and younger voters, calling for action over inertia, saying "Under this rule a relatively small clique of people choose governors nearly 10 years in advance, supporting them up a series of political steps to the highest office." Gibson defeated Proctor and won the general election in 1946, in what was called "a repudiation by Vermont voters of political practices and traditions that have been long established – a rebellion, not against outright mismanagement and inefficiency in the
state government at
Montpelier, but rather against the inertia and lack of aggressiveness of administration policies." He won reelection in 1948 and served from January 1947 to January 1950. During Gibson's first term, he concentrated on increasing state services following years of small budgets and limited priorities following the
Great Depression and World War II. He obtained approval of plans to expand and modernize state highways, improve health services, and enhance education and social welfare programs. To raise the funds necessary to support the largest budget in state history ($31 million), Gibson advocated for and obtained an increase in the state income tax. Gibson resigned to become a federal judge and was succeeded by
Harold J. Arthur. ==Federal judicial service==
