The founders of the KKK may have been Democrats, I wouldn't doubt it. Most Black people in America who have been here for several generations have family members who owned slaves. America made it legal to rape slaves vis Partus Ventrum Sequitur though many slave owners don't appreciate that's what it was. Thats how in just a few generations we got quadroons and octaroons. Sally Hemings was the product of Jefferson's father-in-law raping her mother whose mother was raped by a white man before her. Thomas continued the family legacy by raping a 14-year-old Black girl. If Harris's father's family owned slaves. What do you think that means?

The Republican Party deserves great credit for some of their early deeds including ending slavery. They also (combined with Democrats) ushered in Jim Crow and ended Reconstruction with the Compromise of 1877 and Posse Comitatus.

Trump's racism is well documented in his own words. You have the Internet; look them up. I won't say all his supporters are racist, they are just comfortable supporting racist policies and looking the other way.
