By the mid-20th century, US populism had moved from a largely progressive to a largely reactionary stance, being closely intertwined with the anti-communist politics of the period. In this period, the historian Richard Hofstadter and sociologist Daniel Bell compared the anti-elitism of the 1890s Populists with that of Joseph McCarthy. Although not all academics accepted the comparison between the left-wing, anti-big business Populists and the right-wing, anti-communist McCarthyites, the term "populist" nonetheless came to be applied to both left-wing and right-wing groups that blamed elites for the problems facing the country. Some mainstream politicians in the Republican Party recognised the utility of such a tactic and adopted it; Republican President Richard Nixon for instance popularised the term "silent majority" when appealing to voters. Right-wing populist rhetoric was also at the base of two of the most successful third-party presidential campaigns in the late 20th century, that of George C. Wallace in 1968 and Ross Perot in 1992. These politicians presented a consisted message that a "liberal elite" was threatening "our way of life" and using the welfare state to placate the poor and thus maintain their own power.
