Essentially, today’s 213-member Democratic caucus breaks down into a few categories, the largest of which are traditionally liberal lawmakers who come from cities or inner suburbs and are comfortable with incremental victories in helping the working class. There are dozens of moderates who are more friendly toward business but believe in socially liberal values.

And there are dozens of far-left liberals, hailing from the progressive caucus or the small-knit “Squad,” who have clashed with leaders for not pushing for a more purely liberal agenda. This group has been on the rise over the past half decade, both at the ballot box and inside the caucus.

But now, at this stage of the primary calendar, this wing is facing tough political headwinds.
