> I perceived (and I thought many other people did also) as Sanders running more on economic issues (equality, taxes, etc) and Hillary running more on social justice issues (deplorables, "woman card", equal pay, immigration, racial justice, etc)

Most of the notable Democratic candidates are running far more heavily on economic issues than Clinton was, and even the more centrist ones like Gillibrand are campaigning on things that in 2016 were Sanders-exclusive signatures, like Medicare for All. Clinton may have won the 2016 nomination, but Sanders was a lot more influential on the trajectory of the party.
