This is it, basically. If we have two terms of Clinton and a term of Kaine, or someone similar to Kaine, then we end up with a Centrist party in the Democrats and a far Right opposition in the Republicans, with essentially no viable Left.
More specifically, I think something more dramatic needs to be done about financial inequality, which is the fount of most social tensions as well IMO. The old Democratic "tax the rich and close loopholes" mentality doesn't really work, because the people such policies target simply disguise their money, move it elsewhere, find still other loopholes, etc. Under Clinton the mammoth budgetary allotment to the military will likely continue as well.
And I get that Bernie was more rhetoric than hard policy on wealth disparity, but I do think he would have made it a high priority as president.
