Update.

The Congressional Quarterly of June 26, 1964 (p. 1323) recorded that, in the Senate, only 69% of Democrats (46 for, 21 against) voted for the Civil Rights Act as compared to 82% of Republicans (27 for, 6 against). All southern Democratic senators voted against the Act. This includes the current senator from West Virginia and former KKK member Robert C. Bryd and former Tennessee senator Al Gore, Sr. [...]

As correctly pointed out above, Democrats and Southern Democrats are two different things entirely. Republicans used to be the yankee party, and no self-respecting southerner would vote for them. They had their own special breed of Democrat, who were more right-wing than Pat Buchanan.
See also yellow dog democrats and "Dixiecrats" (Ultimately, the Dixiecrat movement paved the way for the rise of the modern Republican Party in the South. Many former Dixiecrat supporters eventually became Republicans, as was highlighted by Strom Thurmond's conversion in the 1960s).
