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.
Left–right political spectrum
A number of significant political movements—including feminism and regionalism—do not fit precisely into the left-right spectrum. Though nationalism is often regarded as a right-wing doctrine, many nationalists favor egalitarian distributions of resources. There are also "liberal nationalists". Populism is regarded as having both left-wing and right-wing manifestations (see left-wing populism and right-wing populism). Green politics is often regarded as a movement of the left, but in some ways the green movement is difficult to definitively categorize as left or right.
