Conservative Democrat
After 1980, the Republicans became a mostly right-wing conservative party, with conservative leaders such as Newt Gingrich, Trent Lott, and Tom DeLay, while the Democrats, while keeping their core liberal bases intact with such Senators as Ted Kennedy, Christopher Dodd, and Paul Sarbanes, grew a substantial moderate/centrist wing, the New Democrats, in the 1990s in place of their old conservative wing, with leaders such as Bill Clinton, Al Gore, and Evan Bayh. In the 2010 midterm elections, many conservative Democrats lost their seats to the Republicans.
Right-wing populism
Moore (1996) argues that "populist opposition to the growing power of political, economic, and cultural elites" helped shape "conservative and right-wing movements" since the 1920s. Historical right-wing populist figures in both major parties in the United States have included Thomas E. Watson, Strom Thurmond, Joe McCarthy, Barry Goldwater, George Wallace and Pat Buchanan. When Conservative Democrats dominated the politics of the Democratic Party, they comprised a faction of the Democrats which espoused populism, while the Republicans have adopted some forms of populism since 1980s.
