He was a delegate to the Democratic National Conventions in 1948, 1952, and 1956. In 1944, he ran for Governor of Montana, winning the Democratic primary and advancing to the general election, where he opposed Republican incumbent Gov. Sam C. Ford.

Wheeler in the Democratic primary in 1946, and though he ended up defeating Wheeler in an upset, he lost the general election to Republican State Senator Zales Ecton. He ran for governor once more in 1948, but finished third in the Democratic primary behind former Montana Attorney General John W. Bonner and Arthur Lamey.
