Gardiner was elected as a member of the
Maine House of Representatives in 1920. He held that position for six years. In 1928, he was nominated by the Republican Party for the governorship of Maine. He won the general election by a popular vote. He was successful in his re-election bid in 1930. During his administration, when the stock market crashed, the crippling economic problems were dealt with. He left office on January 4, 1933. During World War II Gardiner returned to the Army, serving in the
United States Army Air Forces as a staff officer. While assigned as Intelligence Officer of the
51st Troop Carrier Wing in North Africa, he joined Brigadier General
Maxwell D. Taylor, artillery commander of the
82nd Airborne Division, on a clandestine mission behind Axis lines in Italy on September 7–8, 1943. Meeting with Italian prime minister Marshal
Pietro Badoglio and General
Giacomo Carboni, the pair had been sent to assess the chances of success of an airborne operation to seize two airfields near Rome in advance of the
Allied invasion of Italy at
Salerno, and the credibility of Italian assurances of cooperation. As a result of the meeting, the proposed operation was cancelled at the last minute and a disaster averted. == Personal life ==
