Then why is it the none of the Southern Republicans supported the Civil Rights Act of 1964?

I suspect most of the region's Republicans supported Civil Rights in 1964. There just wasn't many of them in office in 1964. The career of Frank Johnson of Alabama is good place to start if one is interested in learning of pro-civil rights southern Republicans.

My mistake the Civil Rights Act was in 1964.

However, no Republicans from the South voted for the Civil Rights Act of 1964.
