After returning to Mississippi to live, in 1972 Meredith ran for the US Senate against the Democratic senator James Eastland, who had been the incumbent for 29 years in what had operated as a one-party state. Following provisions of a new state constitution in 1890 that made voter registration extremely difficult, African Americans had been effectively disenfranchised and the Republican Party had been crippled. Meredith conceded that he had little chance of winning unless Governor George Wallace of Alabama entered the presidential race and split the white vote.
