Continued response to Rick Wicks:
1964, Current Civil Rights Act passed and signed by Lyndon Johnson with 80% republican support and 68% democrat support.
1965, Voting Rights act passed and signed, again with a very large majority of republicans voting for it and a much smaller majority of democrats voting for it.
1973, The democratic party adopts Margaret Sangers Eugenics program which was partially titled "Negro Population Control". Ms Sanger is the founder of Planned Parenthood.
Since that time, there have been very few republicans switching to the democratic party but much more democrats switching to the republican party for economic reasons, not race issues as your side believes.
Restricting voting to legal American citizens has done nothing at all to restrict the ability to vote for anyone.
If you want to find racism, which party always identifies race and which party does not. The republicans do not identify race so which is racist? Kind of logical which party uses race
