Righties always trot out that Dems started the KKK. This is true. What the Righties always leave out, because it doesn't fit their agenda, is that the KKK-loving Dems were conservative Dems. These conservative remained Dems until Richard Nixon enticed them over to the Republican party in the late '60s.
It didn't take much enticing after LBJ signed the Equal Rights Act of 1964. They automatically became republicans.
