Goldwater voted against the so-called (1964) Civil Right Act because he thought it was an unconstitutional overreach by the federal government.
Your blanket comment that Goldwater was against civil rights is interesting. May we see your data?
Goldwater was against the civil rights act of 1964 and that was all it took to flip the white south to the Republicans and to flip the blacks of the USA to the Democrats. That is the truth. I was there in the south and saw it happen.
