Coincidence?

The Civil Rights Act of 1964 was approved by about 7% of Southern Democrats, known as the Dixiecrats. From that time on into the 1990’s the South, which had once been primarily Democratic, became predominantly Republican, with many of the Dixiecrats joining the Republican Party whose Southern members had overwhelmingly opposed the Act.

Today the hard right wing of the Republican Party is dominated by Southern Republicans. Draw what conclusions you will.
