Way misleading; the majority of both parties voted for the Civil Rights Act of 1964. All Democrat opponents were from the South (possibly Robert Byrd too), but only one Republican, John Tower, who later "repented". Strom Thurmond, who voted no and also "repented", switched parties some two months later.
Thanks! You are correct. Didn’t mean to mislead. I should have said it was a republican majority congress at that time or a majority of congress voted for the act, the opposed members were mostly southern democrats.
