So why was the old south Democratic until 1964, and Republican ever since? lol
The South was reliably democrat until 1968 when Nixon used his "southern strategy" to polarize the nation because of the anti war protests. Blacks took this inopportune moment in history to begin a violent black power movement that further pushed southern democrats away.
The Southern Strategy was implemented in the 1968 Richard Nixon-Hubert Humphrey election. In the Southern states, voters were concerned about state order and law enforcement. There were frequent reports of rioting young Americans burning army draft cards and US flags in response to the Vietnam War, African-American students rioting and the 'hippy movement', drugs, and 'free love'.
All of these factors concerned the Southern white population, a deeply Christian and patriotic part of America: the reports scandalized many and created a concern about law and order. After the assassination of Martian Luther King, the Civil Rights movement became a more freely violent movement with the relationship between whites and blacks becoming more fractious. Other causes of unrest were the long and unpopular Vietnam War, and the notion of Black Power.
