The Progressive Democrats of America is a grassroots Political Action Committee (PAC) that functions within the Democratic Party. Progressive Democrats combine some ideals of the Democratic Party with those of the nonpartisan progressive movement
Modern liberals and progressives constitute roughly half of the Democratic voter base. Liberals thereby form the largest united typological demographic within the Democratic base. According to the 2008 exit poll results, liberals constituted 22% of the electorate, and 89% of American liberals favored the candidate of the Democratic Party. college-educated professionals were mostly Republican until the 1950s; they now compose perhaps the most vital component of the Democratic Party. A large majority of liberals favor universal health care, with many supporting a single-payer. A majority also favor diplomacy over military action, stem cell research, the legalization of same-sex marriage, secular government, stricter gun control, and environmental protection laws as well as the preservation of abortion rights. Immigration and cultural diversity is deemed positive, a system in which immigrants retain their native culture in addition to adopting their new culture. They tend to be divided on free trade agreements and organizations such as the North American Free Trade Agreement (NAFTA). Most liberals oppose increased military spending and the display of the Ten Commandments in public buildings.
This ideological group differs from the traditional organized labor base. According to the Pew Research Center, a plurality of 41% resided in affluent households and 49% were college graduates, the highest figure of any typographical group. It was also the fastest growing typological group between the late 1990s and early 2000s. Liberals include most of academia and large portions of the professional class.
