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.
Libertarian socialism
Left communism is the range of communist viewpoints held by the communist left, which criticizes the political ideas of the Bolsheviks at certain periods, from a position that is asserted to be more authentically Marxist and proletarian than the views of Leninism held by the Communist International after its first and during its second congress. Left communists see themselves to the left of Leninists (whom they tend to see as "left of capital", not socialists), anarchists (some of whom they consider internationalist socialists) as well as some other revolutionary socialist tendencies (for example De Leonists, who they tend to see as being internationalist socialists only in limited instances). Although she lived before left communism became a distinct tendency, Rosa Luxemburg has heavily influenced most left communists, both politically and theoretically. Proponents of left communism have included Amadeo Bordiga, Herman Gorter, Anton Pannekoek, Otto Rühle, Karl Korsch, Sylvia Pankhurst and Paul Mattick.
