Sorry there were some democrats who didn't fit your bill. But you don't get to pick and choose who represents your party after the fact. They were elected as dems... they voted as dems..... they were dems. All you're doing is spinning history cause you didn't like it's results. You sound like Emily when she makes her argument that the dems are perfect.
1964 Civil Rights Act - Aye Votes
House Dem/Union - 144/152 (95%)
House GOP/Union - 137/161 (85%)
Senate Dem/Union - 45/46 (98%)
Senate GOP/Union - 27/32 (84%)
House Dem/Confed - 8/91 (9%)
House GOP/Confed - 0/11 (0%)
Senate Dem/Confed - 1/21 (5%)
Senate GOP/Confed - 0/1 (0%)
Taking into consideration, 8 Dem/Union House Reps out of 152 and 1 Dem/Union Senator out of 46 voted against the Civil Rights Act... yes, you are ten million percent correct when you say "some."
What the numbers above tell me is 1. the vote was based more on region than political affiliation and 2. more Democrats than Republicans voted "aye" and 3. why my family could not get served at a Richmond, VA Ho Jo in the summer of '64.
