I blame Donald Trump. Seriously. I think commentators have become grandiloquent in response to what they feel is his crudeness, his brutality. And look for the words "crude" and "brutal." They're everywhere.
ADDED: It seems that the anti-Trump people are LIKE the pro-Trump people: so theatrically emotional. Maybe it's that everyone, deep down, knows the next president is Hillary Clinton, and it's a pre-freakout.
