I hope she mentions that the Democratic Party supported slavery and its expansion; that southern Democrats played the primary role in secession and the founding of the Confederacy; and that Democrats supported the Ku Klux Klan, segregation, Jim Crow laws, and lynching.
Yes, you are correct. Southern Democrats were at the forefront of slavery, secession, the KKK and Jim Crow. Remember, it was West Virginia DEMOCRAT Sen. Robert C. Byrd (Sheets Byrd himself) who tried to stop the Civil Rights Act. Pres. Johnson need A LOT of Republican support to get that bill passed.
