I don't think Nixon was uncouth. The reason why Watergate was allowed to happen was that Nixon was fed up with and wanted to stop the billions of dollars america was funding Israel each year. He wanted to use those funds to uplift the people of the same background as him, namely White working class americans. He didn't want anything to do with Israel or the Middle East. However, Nixon was a racist and did not particularly like Blacks, Jews or indians. In the Watergate tapes, him and Ronald Regan can be heard to be making disparaging racist remarks against all three ethnic groups listed above.
