Bob Woodward and Robert Costa of the Washington Post interviewed Donald Trump this week. The interview was described as “very unusual” by Woodward. The headline makers used that phrase to further validate a narrative that Trump is a kook. But when you watch a video of the two reporters discussing the interview the impression is that “unusual” is not intended as “odd” or “strange” in a pejorative sense, but “different” from traditional behavior in presidential politics. Framing Trump as a nut may be a mistake that his opponents use as a primary theme to their peril.
