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 coalition
The conservative coalition was an unofficial Congressional coalition bringing together a conservative majority of the Republican Party and the conservative (mostly Southern) wing of the Democratic Party. According to James T. Patterson: "By and large the congressional conservatives by 1939 agreed in opposing the spread of federal power and bureaucracy, in denouncing deficit spending, in criticizing industrial labor unions, and in excoriating most welfare programs. They sought to "conserve" an America which they believed to have existed before 1933."
