Haha, no!This stayed that way until the Grant administration when the Republicans abandoned the negro vote and went to bed with big business. The dems filled the void and it has not changed much since.
What really happened was that Republicans was always in bed with big business. Democrats remained racists, but turned further left economically. For instance in 1924 with FDR as a vice president of the Democrat ticket, Democrats debated if they were going to distance themselves from KKK.
Then in 1933 they got the power because people were angry at big business, but Republicans did not take Democrats place just yet. That only happened in 1960. Before that Democrats were racist and left wing economically and the majority of blacks voted Republican.
