For one, you're wrong as usual, but like to use your Wikipedia sources to make a point that wasn't even the original point. The point was was that President Johnson, a Democrat continued with President Kennedy's work to pass a Civil Rights bill. Not a Republican, but a Democrat.
Now I want you to go back to Wikipedia and tell how many southern Democrats voted for it? And how many Republicans voted for it?
Also, to try and make it seem like Republicans were for Civil Rights for blacks? What was Nixon's Southern Strategy? Don't know? Don't wanna say? Allow me then...
Nixon's "Southern Strategy" was appealing to Democratic whites who were unhappy with desegregation and played on their hatred and fears to when those votes. That is why southern whites are no longer with the Democratic party anymore.
Stop cherry-picking to make your point, and stay off Wikipedia.
