In 1868, Pettit was elected assistant
reading clerk in the
Kentucky House of Representatives, a position he held for six years. Estranged from the Democratic Party by his refusal to identify with them during his race for the House, Pettit became a leader of the Populist Party in Kentucky. Redistricting and an inefficient legislative session were factors in the defeats of several Populist candidates during the 1893 elections. He received the endorsement of
Louisville's
New South newspaper, one of the largest
black newspapers in the state. The
American Protective Association (APA), an influential society opposed to
Catholicism, endorsed the entire Republican ticket except the party's gubernatorial candidate,
William O. Bradley. The APA withheld its endorsement from Bradley because of rumors that some of his family members were Catholic, and the society was thought to favor Pettit until Bradley was reported to have joined the society in September 1895, forestalling their endorsement of Pettit. In the general election, Pettit garnered 16,911 votes, compared to 172,436 for Bradley and 163,524 for Hardin. Although he had not been elected, his presence on the ballot had taken a significant number of Democratic votes from Hardin and resulted in the election of Bradley, Kentucky's first Republican governor. ==Later life and death==
