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.
Christian right
Evangelical leaders like Tony Perkins of the Family Research Council have called attention to the problem of equating the term "Christian right" with evangelicals. Although evangelicals constitute the core constituency of the Christian right, not all evangelicals fit the description and moreover, a number of Roman Catholics are also members of the Christian right's core base. The problem of description is further complicated by the fact that "religious conservative" may refer to other groups. Mennonites and the Amish, for example, are theologically conservative, however there are no overtly political organizations associated with these denominations.
