Not exactly. Democrats are still racist as all heck. And they pretend they aren't. I think Malcolm X was the one that pointed out that they pretend to be your friend just to use you.
Republicans have definitely gone down hill though. At best they are do nothing's, at worst they are racists that don't hide it.
I personally find it amusing that the Klan has the self awareness to use their bad rep to make Republicans look bad by pretending to support them.
