As the civil rights movement and the dismantling of Jim Crow laws in the 1950s and 1960s deepened existing racial tensions in much of the Southern U.S, a Republican Party electoral strategy – the Southern strategy – was enacted in order to increase political support among white voters in the South by appealing to racism against African Americans. Republican politicians such as presidential candidate Richard Nixon and Senator Barry Goldwater developed strategies that successfully contributed to the political realignment of many white, conservative voters in the South who had traditionally supported the Democratic Party rather than the Republican Party. In 1971, angered by African delegates at the UN siding against the U.S. in a vote to admit China and expel Taiwan, then Governor of California Ronald Reagan stated in a phone call to president Nixon, "To see those... those monkeys from those African countries - damn them, they're still uncomfortable wearing shoes!" The perception that the Republican Party had served as the "vehicle of white supremacy in the South", particularly post 1964, made it difficult for the Party to win back the support of black voters in the South in later years.
