The statement that is NOT true about Lester Maddox is:
He openly claimed to be a racist while running for governor of Georgia.
While Maddox was known for his segregationist views and actions, such as refusing to serve African-American customers in his restaurant, he did not explicitly identify himself as a racist in those terms during his political career. Instead, he often framed his beliefs in terms of states' rights and opposition to federal mandates regarding integration.
