The us democratic party mostly includes members who are

The Democratic Party is, together with the Republican Party, one of the two main political parties of the United States of America. The Democratic Party is considered a liberal and progressive party.

However, the reality is that it is a party with a great and multifaceted ideological divergence that houses different ideological sectors within its ranks ranging from the center-right conservative, through the center, classical liberalism, socioliberalism, social democracy, sectors union, labor, progressive and left. These sectors can be dominant according to the historical moment, for example, conservative Democrats, almost all Southerners, were allied with the Republicans in the so-called "Conservative Coalition", an informal coalition that dominated the Senate from 1937 to 1961.

Defining the trend of the current Democratic Party is quite difficult. Broadly speaking, it can be said that it represents liberalism in the United States, but within it coexist diverse ideological groups that include conservatives, liberals, progressives, social democrats, centrists and even socialists. In the Senate, for example, the Democratic side is allied with two independents, Joe Lieberman considered a conservative, and Bernie Sanders self-proclaimed socialist, which gives an idea of the ideological diversity in Democratic Party alliances motivated by political praxis.
