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.
Tea Party Caucus
The Tea Party Caucus is often viewed as taking conservative positions, and advocating for both social and fiscal conservatism. Analysis of voting patterns confirm that Caucus members are more conservative than other House Republicans, especially on fiscal matters. Voting trends to the right of the median Republican, and Tea Party Caucus members represent more conservative, southern and affluent districts. Supporters of the Tea Party movement itself are largely economic driven.
