Are Americans angry?

Kevin Drum, Mother Jones

It's now conventional wisdom that explains Donald Trump and Bernie Sanders: American voters are pissed off. A few of the latest examples here and here.

Kevin Drum challenges the conventional wisdom:

So why are voters so angry? That's a good question, except for one thing: it assumes that voters are angry in the first place. It's true that if you go out and talk to people, you can find plenty of angry folks. That's always the case, but it's completely meaningless. The only interesting question is: Are Americans angrier than usual? It sure doesn't look like it, does it? You can take a look at every poll you want, and what you'll find is that, generally speaking, Americans just aren't unusually unhappy or unusually angry right now. They just aren't. There's virtually no serious data to suggest otherwise...
