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-wing politics
The spectrum of left-wing politics ranges from center-left to far-left (or ultra-left). The term center-left describes a position within the political mainstream. The terms far-left and ultra-left refer to positions that are more radical. The center-left includes social democrats, social liberals, progressives and also some democratic socialists and greens (including some eco-socialists). Center-left supporters accept market allocation of resources in a mixed economy with a significant public sector and a thriving private sector. Center-left policies tend to favour limited state intervention in matters pertaining to the public interest.
