Starting in 1972, following Richard Nixon's presidency, the United States shifted away from a system of political bosses. This was achieved by broadly expanding primaries at all levels. Rather than bosses selecting candidates and controlling them, direct democratic elections were used for candidate selection. Since the bosses didn't select candidates, the candidates were beholden to the voters rather than the bosses. Each election year, the voters would select the candidates and then select the officeholder. Over time, the power of the political machine was broken and replaced by a series of elections. The founders did not want this level of democracy, but neither did they explicitly want the party boss.
