In 1883, Baker became a member of the Prohibitionist party. It was his affinity for temperance that led him to invite Emma Molloy to move to the Ozarks after meeting her at one of her revivals. Baker was remembered for his “courageous defense of Mrs. Molloy, who was persecuted because she was a temperance advocate…”
His support of Emma apparently did not damage his political aspirations; in September 1886, he was elected chairman of the Missouri Prohibitionist party.
Baker died in 1910 at his sons home in New Lenox, Illinois. He was returned to Springfield and is buried in the National Cemetery. His wife, Maggie, died in 1924 at their home in Evanston, Illinois.
