That link right up there I think describes fully the DSA and progressive caucus.
Here’s a snip from link:
“DSA recognizes that some insurgent politicians representing labor, environmentalists, gays and lesbians, and communities of color may choose to run under Democratic auspices, as in the 1988 Jesse Jackson campaign, or operate as Democrats like Senator Paul Wellstone, and the 59 Democratic members of the Congressional Progressive Caucus, one-half of whom are Black and Latino and all of whom possess strong labor backing and operative social democratic politics.”
