Although he was still not free, Turner operated a number of his master's businesses in Selma, Alabama. The end of slavery and extension of voting rights for black men under the 14th and 15th Amendments provided Turner with the opportunity to enter politics as a member of the short-lived biracial coalition of former slaves and white Southerners who hoped to challenge the control of planters. Turner joined the Republican Party and served as a tax collector in Selma before winning election to the city council on the Republican ticket.
After two years in the city council, Turner won election to Congress and represented Alabama's First District from 1871 to 1873. Turner was defeated in his attempt to win reelection in 1872, as the black vote was split between him and Philip Joseph, another African American candidate. Turner returned to business after serving in Congress but the end of Reconstruction and a national recession limited economic opportunities for African Americans and travelers, a consequence that contributed to the closure of his hotel. Turner, like many African Americans, returned to farming in hopes of earning enough money to purchase land and escape debt. He passed away in 1894.
