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.
Conservative wave
The subsequent economic crisis of 2015 and investigations of corruption scandals led to a right-wing movement that sought to rescue ideas from economic liberalism and conservatism in opposition to left-wing policies. The growing numbers and influence of strongly socially conservative and prosperity theology-believers among the evangelical Christian communities in Latin America has also been pointed as one of the factors behind the phenomenon.
