I’m back to inviting readers to submit quotations whose origins they want me to try to trace, using my book, The Yale Book of Quotations, and my more recent research.
James Curran asked:
Considering the unrest in the Middle East, I’m reminded of this widely attributed saying. Can you track down by whom and about whom the following statement was first made? “He’s a son-of-a-bitch, but he’s OUR son-of-a-bitch.”

Do any readers have any other quotations whose origins they would like me to attempt to trace?

pps: Why aren’t you listed as a contributor on Freakonomics?

“Unofficial Observer” [pseud., John Franklin Carter]:
After the Chicago Convention, General Hugh Johnson, who had worked hard with Barney Baruch to stop
Roosevelt, was asked what he thought of his nomination. Johnson replied by recalling a story of a county
convention of Democrats in which the wrong man had been chosen. Driving home from the meeting,
two politicians were comparing notes. Both had opposed the successful candidate. One said to the other,
“Damn it all! we should never have let them put Blank over. He’s a son-of-a-bitch.” The other man sighed and
said nothing for a long time. Then he cheered up. “After all,” he observed, “Blank isn’t so bad. He’s _our_ son-of-a bitch!” A year later, Johnson was one of Roosevelt’s principal administrators…
