Presumably Trump knows the Pledge of Allegiance and the chorus to the song. I doubt he’s ever read any other parts of this bible he’s hawking, certainly not the constitution. I’d also like to reference an alternate form of the Pledge of Allegiance I first read from Matt Groening of The Simpson’s fame from his comic strip Life in Hell:

I plead alignment to the flakes of the entitled snakes of a merry cow. And to the republicans for which they scam: one nacho, underpants with licorice and jugs of wine for owls.

Somehow this seems surprisingly relevant now, (I know he did other forms of the pledge of allegiance but this is the one that stuck with me.)
