What if this is the end of right vs. left?

Something the family was just kicking around the dinner table, as we realized that -- for the first time ever -- we will be voting differently from our dearest lefty compatriots (who despise Hillary and can't be talked out of voting for Stein), but are being joined in supporting Hillary by our Republican family and friends:

Suppose Hillary achieves a crushing victory -- and a large part of that victory comes from crossover votes from "sensible Republicans," of the sort that used to be abundant in the Northeast and Midwest in particular (i.e., economic conservative/social liberal types; and yes, they still exist).

Suppose Trump makes good on his plan to label his loss a rigged election -- and he's joined not only by his Neanderthal followers but by the BoBs who have already been claiming Clinton victories are the result of rigging the vote.

Hillary still wins, of course (hurrah!). And teh Democratic Party is bigger than ever (hurray!). But American politics reconstitutes into the Party of the Governing Class and the Party of Angry Malcontents -- or the Party of Shore It Up and the Party of Burn It Down, as I like to think of it. Are you ready to be part of the Governing Class Party? I am, I guess, but I'm a middle-aged white guy with privilege to spare; it seems like a funny position for the Democratic Party as a whole to be in -- especially if Meg Whitman et al. decide to stay and make themselves at home...
