1. The party of slavery was also the party of people in the north who did not have slaves.
2. Democrats were the majority in the south, until the election of 1860 when they formed their own party because the democratic party was not supporting their claims related to slavery and the return of escaped slaves.
3. Democrats continued to control elected offices in the south until 1964...then they began to switch to the republican party. Same time the blacks started to switch from republican to democrat.

2. They went from Democrat to Democrat and in 1865 to being Democrat.
3. What switch?
