Unfortunately Goldwater's anti-Civil Rights stance cost the Republicans the great bulk of Black voters it had enjoyed previous to the '64 election. In 1960 Richard Nixon received fortyfive percent of the Black vote. Goldwater received a much smaller percentage.
This is one of those liberal historical lies (they DO know better) masquerading as history.
The fact is that Barry Goldwater had voted for every civil rights bill up until the 1964 one, which contained the seeds of wat would become the Affirmative Action program. Goldwater said it was unconstitutional, and it was. He alsopredicted that it would result in racial preferences an quotas and even made a gentlemen's bet with Senator Humphrey that it would. Barry was right, as usual.
