I would agree, though I would say the Democratic party is not tearing itself asunder the way the Republicans appear to be doing, but has politely shifted left. For avid observers of politics this could be a very interesting year.Hillary has the same problem with Bernie supporters. Many Bernie voters refuse to support Hillary and side with Trump on deindustrialization. Cross-over will be a hallmark this election cycle. Neocons will cross-over and vote Hillary. Independents and Reagan democrats will cross-over and vote Trump. This is the realignment happening between establishment fuckboys and outsider populists. Plenty of losers in both parties support establishment candidates. And plenty of nationalists in both parties who want to see the establishment die an ugly death. Hence the "big realignment".
Hillary must cede a big position to Sanders. Perhaps VP. The biggest story of the year is the Democratic Party is tearing itself up slightly less then the Republican party.
