Why was there a white backlash in Georgia against the Repúblican party

It was the summer of 1964, and Lyndon Johnson was scared. Having just achieved one of the greatest congressional victories in history by passing the Civil Rights Act (CRA) over the strident objections of his native South, Johnson was now confronted by black riots in several urban centers. He feared that his Republican opponent, Barry Goldwater, would exploit the racial turmoil by appealing to the white backlash. The riots were even labeled "Goldwater rallies" since the conflagrations helped the GOP so directly. Would racial politics cost LBJ the White House?

Both Johnson and Goldwater would face several tests of their character in the long election season of 1964, tests involving the CRA, urban riots, the George Wallace candidacy, and the white backlash. The election of 1964 is considered by many to be the most racially polarized presidential contest in modern American history. As such, it has been seen as a watershed in the evolution of our two-party system in recent times.2 Yet what has been missed in previous analyses of 1964 is how assiduously both Goldwater and Johnson worked to take race off the agenda. Johnson believed that if the election became a referendum on civil rights, he might lose. Goldwater believed that history would judge him harshly if his campaign blatantly exploited the racial hatred of whites.

Still, despite these efforts, the racial implications of the 1964 campaign would linger for decades. The first Southerner to occupy the White House for more than a hundred years lost the heart of his region, signaling the dawn of an era of Republican dominance of the South in presidential politics. The first man of Jewish descent to run on a major ticket 3 would lead the Republican Party into a monochromatic whiteness from which it has not yet recovered. After 1964, Democrats could take the black vote for granted as the GOP became the party through which whites expressed their unease over black progress. The contest between Johnson and Goldwater shaped American racial politics for the next thirty-six years.
