Answer:
The Southern strategy refers to the strategy put in place by the Republican Party to seduce the white electorate of the South of the United States who traditionally voted Democrat. This was the main strategy of Richard Nixon's campaign during the 1968 presidential election.
Explanation:
Republicans dominate the southern US since they managed to win the conservative and racist white vote thanks to the so-called "southern strategy" launched by President Richard Nixon in 1968. This was a successful offensive to capture these voters, irritated with the support of the Democrats to the campaign of civil rights for the blacks, who threw themselves into the arms of this party while the white conservatives allied themselves with the Republicans.
