Electoral politics and office-holding members
In electoral politics, the DSA was very strongly associated with Michael Harrington's position that "the left wing of realism is found today in the Democratic Party".
In its early years, the DSA opposed Republican presidential candidates by giving critical support to Democratic Party nominees like Walter Mondale in 1984. In 1988, the DSA enthusiastically supported Jesse Jackson's second presidential campaign. Since 1995, the DSA's position on American electoral politics has been that "democratic socialists reject an either-or approach to electoral coalition building, focused solely on a new party or on realignment within the Democratic Party". During the 1990s, the DSA gave the Clinton administration an overall rating of C-, "less than satisfactory".
The DSA's elected leadership has often seen working within the Democratic Party as necessary rather than forming or support third parties. That said, the DSA is very critical of the Democratic Party leadership, which the DSA argues is corporate-funded. The organization has stated:
Much of progressive, independent political action will continue to occur in Democratic Party primaries in support of candidates who represent a broad progressive coalition. In such instances, democratic socialists will support coalitional campaigns based on labor, women, people of color and other potentially anti-corporate elements. Electoral tactics are only a means for democratic socialists; the building of a powerful anti-corporate coalition is the end.
The DSA now has many far more destructive 'burn it all down, destroy the Dems too' forces in it, and the actual Communist (real Communists, even revanchist Stalinists) quotient has increased.
