McMullen was born in Wellsville, New York and as a young boy moved with his family to Wymore, Nebraska. He was a founding member of the Beta Tau Chapter of Delta Tau Delta Fraternity at the University of Nebraska-Lincoln in 1894. He graduated from the University of Nebraska in 1896, and matriculated at George Washington University, where he earned a law degree in 1899. He was married to Cora Greenwood.
Still in Washington, D. C. after his graduation in 1899, McMullen worked as a secretary for Nebraska Congressman, Jesse Strode, then for Senator Charles Henry Dietrich. He returned to Wymore, Nebraska where he passed the state bar and entered into private practice. Elected into the Nebraska House of Representatives, he served two terms from 1904 to 1908.
In 1906 McMullen was elected to the Nebraska State Senate and served from 1907 to 1909. From 1916 to 1920 he was a member of the Wymore School Board, serving as president during the last two years. He was elected Governor of Nebraska in 1924 and in 1926. During his tenure, the state deficit was erased by implementing a special tax, and the state highway program was improved.
After stepping down from governorship, McMullen settled in Beatrice, Nebraska and continued to stay politically active while pursuing his own business interests. He served as Postmaster of Beatrice in 1932. He was also a delegate to 1944 Republican National Convention and the chairman of the National Governors Association in 1927 to 1928.
