Born near Dixon, Illinois, Hamilton moved to Miami County, Kansas, with his parents, in 1868 and to Prairie Township in Keokuk County, Iowa, in 1874. He attended the country schools and graduated from the University of Iowa College of Law in June 1884.
In November 1906, Hamilton ran as a Democrat against longtime Republican Congressman John F. Lacey in the general election for Iowa's 6th congressional district. After defeating Lacey, Hamilton became the only Democrat in Iowa's congressional delegation in the Sixtieth Congress. He ran for re-election in 1908, and won renomination from his party's district convention. However, in a general election in which Republicans swept all major races on the ballot in Iowa, Hamilton was defeated by Republican Nathan E. Kendall in a close race. In all he served in Congress from March 4, 1907 to March 3, 1909.
He resumed the practice of law in Sigourney. In 1918, he was elected judge of the district court of the sixth judicial district of Iowa, in which capacity he served until his death in Rochester, Minnesota, on August 21, 1936. He was interred in No. 16 Cemetery, near Thornburg, in Keokuk County.
