JD Vance has published a prayer that was sent to him by a priest before he went on stage for the vice-presidential debate on 1 October in New York.

Both the religious and non-religious may well agree that, whether an answered prayer had anything to do with it, Vance’s speech was indeed “refined” during the debate with Democratic vice-presidential nominee Tim Walz that Vance is roundly judged to have won. And that, as per the invocations of the prayer, Vance demonstrated “keenness of mind”, “skill in learning” and “eloquence” that has unnerved both the Democratic ticket and much of the mainstream media that is supporting it.
