Life and political career
Smith was born May 23, 1827, in Franklin County, Kentucky, before moving to McLean County, Illinois. He was involved in Republican politics since the founding of the party and was unafraid to espouse his anti-slavery beliefs. He was a delegate at the Illinois State Republican convention in 1860 and nominated Abraham Lincoln for the presidency.

He was elected to the Illinois House of Representatives in 1866, 1868, and 1870. He fiercely opposed the policies of Andrew Johnson, and was known to Illinois newspapers as "The Duke of Lexington" due to his strong personality. He spent his last two years in the legislature as Speaker of the Illinois House of Representatives. After Shelby M. Cullom was elected Governor of Illinois he appointed Smith to the board of the Railroad and Warehouse Commission, where he remained until ill health compelled him to resign. Smith resided in Lexington, Illinois, where he farmed and dealt in cattle. He was a member of the Methodist Church and was married to Nancy Hopkins with whom he had one daughter.

Death
On March 25, 1886, Smith committed suicide by gunshot in a barn on his farm.
