Is it an affectation that they’re trained to deploy? (If so, why?) Or is it just a natural thing that happens in the very specific circumstance of being a politician on the campaign trail, and that’s why no one else seems to do it?
I don’t think I’ve seen it in any other context 🤔
Cheers!
It’s more of a public speaker thing than just a politician thing, but… Well, politicians are all public speakers, so it makes sense that that’s the context you’ve seen it in.
It’s literally a practiced gesture - public speaking makes use of some gestures that telegraph well to crowds, but seem unusual otherwise. IIRC, that fishing rod grip is an alternative to gesturing with a fist - it looks less aggressive, but gets the point across.
