Who have turned the South from Blue to Red
Yeah, two generations later. These aren't the same people that were there 50 years ago.
Oh Really? The defection of Southern Democrats to the Republican party began in 1960s and gained momentum in 70's and 80's with such noted segregationist as:
David Duke, Grand Wizard of KKK
Strom Thurmond, US Senator from South Carolina
Harry F. Byrd, Senator from Virginia
Jesse Alexander Helms, Jr, US Senator from North Carolina
James F. Byrnes, Governor of South Carolina
Trent Lott, US Senator from Mississippi
Yes, conversion of the South did take generations. Even with Eisenhower's milk toast support of the Civil Rights Act of 1957, William H. Buckley Jr's out right support for southern segregationist, and Barry Goldwater's opposition to the 1965 Civil Rights's Act and the Voter's Right Act of 1965, Democrats in the South were slow to abandon the party they had solidly supported for a hundred year. However, when Kennedy and Johnson crammed integration down the throat of southerns, there was no doubt, Democrat control of the South was over.
The coup de gras came with the great communicator Ronald Reagan. Reagan had openly opposed the Civil Rights and the Voter's Rights Act and gave the legislation credit for instigating the urban riots. When he declared war on the big bad federal government which had destroyed segregation in the South, it was music to ears to southern segregationist. Southern whites hated Johnson's welfare programs that were pouring hundreds of millions of dollars into the pockets of poor blacks, so when Reagan attacked Welfare programs, Republicans made even more gains in the South.
