uh yeah but if that's "their" plan it seems like it isn't working, because college kids have been declaring themselves a free commune of everloving fuck for 50 years now and american democrats have only shifted notably left in the past 5
more likely the democratic party is adjusting to a realignment of its coalition and independent constituencies are getting more time in the sun than they would back when unions had a firm grasp on everyone else. one of those constituencies is retard socialists/californians (most of whom are smart enough not to brand themselves as such) which conveniently picks up the college kids, i doubt it happened the other way around.
it'll shake out whenever they win a presidential election again, the wall getting built or trump getting a third scotus pick will probably be major factors. all they learned in 2016 is that you actually need a platform. they will probably mistake no-more-trump for a platform in 2020 just like republicans did with no-more-obama and it will fail in about the same way.
