The South was solidly Democratic. Then several things happened:
- President Truman ordered the US military be desegregated. Southern Democrats were so angry that Truman’s name was not on the ballot in Alabama in 1948.
- Lyndon Johnson passed the Civil Rights Act of 1964 and the Voting Rights Act of 1965.
- White Southerners fled the Democratic Party and joined the Republican Party, thanks to Nixon’s “Southern Strategy”.
And today, the South is solidly Republican because the Republican Party is the party of racial division and hatred.
