A higher percentage of Republicans in the House and the Senate voted for the civil rights Act of 1964.
After reading Shelby Steele's excellent Dec. 18 essay "American Conservatism: Of Race and Imagination" we felt compelled to respond to the popular misconception that "conservatism, for all its commitment to freedom, did not make itself the principled enemy of racism during the civil-rights era." With a little research, the actual voting record for both Houses of Congress shows that the Civil Rights Act of 1964 passed the Senate on a 73-to-27 vote. The Democratic supermajority in the Senate split their vote 46
(69%) for and 21 (31%) against. The Republicans, on the other hand, split their vote 27 for
(82%) and 6 against (18%). Thus, the no vote consisted of 78% Democrats. Further, the infamous 74-day filibuster was led by the Southern Democrats, who overwhelmingly voted against the act.
The House voted 290 to 130 in favor. Democrats split their vote 152
(61%) to 96 (39%) while Republicans split theirs 138 (
80%) to 34 (20%). The no vote consisted of 74% Democrats.
Clearly, the 1964 Civil Rights Act could not have been passed without the leadership of Republicans such as Everett Dirksen and the votes of Republicans.
