this is a false narrative. The democrats were deeply racist for a century after the civil war. all of the jim crow laws were passed by democrats. The KKK was run entirely by democrats. and democrats tried to filibuster the civil rights bill.
democrats want to make it black and white but it isnt. Prior to the civil war, it was almost impossible to find a republican who owned slaves.

But, anyway, was just mentioning the racism of LBJ like everyone else has here
