Neff joined the Democratic Party and entered politics, being elected in 1898 to the
Texas House of Representatives, and serving from 1899 to 1905. He was elected to one term as
Speaker. After returning to his law practice in Waco, Neff served for six years as the assistant county attorney and then as county attorney for
McLennan County. Considered a
progressive Democrat and described as a "friend of organized labor," Neff defeated former U.S. Senator
Joseph Weldon Bailey, a former
populist, in the party primary for governor in 1920. This defeat effectively ended Bailey's political career. Neff handily won the general election and started his term in 1921. During his tenure, a number of reforms were carried out such as new labor laws, the organization of cooperative marketing associations to assist farmers with selling their commodities, and higher funding for vocational and rural schools. Neff received criticism during his time as governor for vetoing a minimum wage act. This was introduced to replace a previous minimum wage law that had been repealed by the Texas Legislature. Much of Neff’s opposition to the measure, however, was directed to the fact that it excluded several categories of workers from its provisions, and in his veto message stated that his veto should not be interpreted as meaning that he did not believe in the possibility of a “just and entirely workable” minimum wage bill. Neff was a strong supporter of
prohibition. He was instrumental in the development of the
Texas State Parks Board. Neff and his mother, Isabella Neff, donated the land which would become the first state park in Texas. It was named
Mother Neff State Park. During the resurgence of the
Ku Klux Klan during his administration, Neff was criticized for not taking a stronger stance. Neff is notable for his pardon of folk singer
Lead Belly in his last days as governor. Neff was reelected in 1922 but did not seek a third term in 1924. At the time, it was "understood" that no governor should run for a third term, although Texas did not have official term limits for the office. In 1924
Miriam Wallace "Ma" Ferguson, wife of controversial former Governor
James E. Ferguson, won the general election. The
Republican nominee,
George C. Butte, a jurist who had opposed James Ferguson's
line item veto of the 1917 University of Texas appropriations bill, had a stronger than usual showing. Many voters crossed party lines to vote for him, as they were unhappy with the corruption associated with "Pa" Ferguson. Neff served as a member of the
Railroad Commission of Texas from 1929 to 1933. ==President of Baylor University==
