Said Ronald Reagan, in 1970, talking about dealing with unrest on college campuses, quoted at the time in
"Ronald Reagan Is Giving ‘Em Heck" (NYT)(free access link).
Later he said the remark was a "figure of speech" and that anyone who took it seriously was "neurotic." Within a few days, four students were shot at Kent State.
I ran across that because I'd noticed that the NYT was spelling "bloodbath" as 2 words — "Trump defends his warning of a ‘blood bath for the country" — in its current reporting. I had 2 theories about why:
1. A compound word takes a long time to become standard. When we see "bloodbath" as one word, it feels more like a stock term. Trite. By spacing it out as 2 words, you might get people to think that Trump put it together in his own fervid brain. But maybe...
2. The NYT has a style guide, and it decided long ago that "blood bath" was the correct configuration, and people at the Times are meticulous about writing it the same way every time.
To narrow my 2 ideas about twoness and oneness down to one, I searched the NYT archive for the 1-word form. I found many examples of "bloodbath," including Reagan's crazy idea of sticking it to the students. There was also Russell Baker making jokes about Richard Nixon's "bloodbath" theory of Vietnam (in 1970, deploying a fictional character he called "Dandy"):
