I've been following Nimh's almost 20 year old thread, "Things people posted that would make perfect sig lines"...and have enjoyed many of the nominations. Many of Tsarstepan's frequent contributions are right on the mark.
That thread came to mind this morning when I read Paul Krugman's opinion column in the New York Times. The comment that caught my attention was too long for a sig tag line, but it certainly could make a great sig comment.
"Speaking of courage, am I the only one struck by the contrast between President Biden’s daring visit to Kyiv and the way President Donald Trump retreated to the White House bunker in the face of unarmed protesters in Lafayette Park?"

For what it is worth, I doubt Krugman is alone there.
