How funny....How many republican senators were there in 1964 from Southern States? There was one. There were 11 republicans in the House from the Southern States.Republicans passed that legislation in by 1872, and your so-called Northen liberals on the Court supported segregation 1896 Plessy v Ferguson.
The Republican Party was not so badly split as the Democrats by the civil rights issue. Only one Republican senator participated in the filibuster against the bill. In fact, since 1933, Republicans had a more positive record on civil rights than the Democrats. In the twenty-six major civil rights votes since 1933, a majority of Democrats opposed civil rights legislation in over 80 % of the votes. By contrast, the Republican majority favored civil rights in over 96 % of the votes.

The numbers show exactly who you are.
All southern republicans voted against...In the Senate there were 21 Southern democrats...all but one voted against. Of Northern Dems all but one voted for.
It is entirely a North vs South issue and the South now has over 100 republicans in congress...vs 12 in 1964.
