The South was not "traditionally Republican run", it was solidly Democratic: "The Solid South was the electoral voting bloc for the Democratic Party in the Southern United States between the end of the Reconstruction era in 1877 and the Civil Rights Act of 1964."[0] Traditionally the "Red" states you opine about were a staunch voting bloc for the Democratic Party.
