Why do seemingly all politicians (and no one else) do that hand gesture when they talk, the one where it looks like they're holding an invisible fishing rod? - eviltoast

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 🤔
