Hunt was sworn in as Arizona's first state governor on February 14, 1912. When the new legislature met in March of the same year, he lobbied for passage of legislation restricting
child labor,
lobbying, and
usury. Other legislation supported by Hunt included requirements for newspapers to disclose their ownership, creation of
workers' compensation, and creating old age pensions. During his first term as governor, several labor laws were introduced. Due to an Arizona Supreme Court ruling that there would be no elections for state officials in 1912, Hunt's first run for reelection did not occur until 1914. After defeating
Ralph H. Cameron, the governor's second term was dominated by events along the
United States–Mexico border. Conflict from the
Mexican Revolution began affecting American interests by April 1914. This was followed by an October 11, 1914 attack on
Naco, Arizona. Hunt considered deploying the Arizona National Guard to protect American lives, but was convinced by
Secretary of War Lindley M. Garrison to allow U.S. Army troops to handle the conflict. Problems with cross border shootings continued with the American military unable to prevent the violence without crossing into Mexico. The elections of 1916 resulted in a contested election result. Initial results showed that challenger
Thomas E. Campbell had won by 30 votes, but Hunt challenged the results claiming that several precincts had experienced fraudulent voting. Hunt initially refused to leave office, but a January 27, 1917, ruling by the Arizona Supreme Court naming Campbell the
de facto governor forced him to surrender his office. On December 30, 1916, shortly before leaving office, Hunt pardoned former sheriff's deputies Robert Fenter and Frank Moore, who had been convicted of second degree murder for lynching two Mexicans suspected of horse theft. The former governor maintained his fights in the court, and on December 22, 1917, was declared the winner of the 1916 election by a total of 43 votes. Hunt returned to office for his third term on December 25, 1917. With the United States' entry into
World War I, Hunt began knitting scarves for soldiers as a patriotic duty and said he wished he could serve with the
U.S. Marines. The governor's associations with the
Industrial Workers of the World however caused his loyalties to be questioned. After a person from
Flagstaff challenged his loyalties, Hunt filed a
lawsuit claiming
libel and was awarded one
cent in damages. ==Minister to Siam==
