Let's suppose we get a purely working class party like the days of old (plus minorities), like the vast majority of Atlasian Democrats seem to want. Which, if we are to use Pew's terminology from that
2014 poll, would mean a Democratic Party composed of mainly Solid Liberals, Hard-Pressed Skeptics, and the Faith and Family Left, while essentially bidding adieu to the Next Generation Left.
That would mean a more socially conservative party in addition to being more economically populist if we want to reflect our altered demographics faithfully.
Is that what you really want?
