I believe he said he read it once in his earlier days.
(Maybe his youth? I feel like it was in his livestream where he responded to a question asking what he's doing to prepare for the debate and he told on himself because he said "well, there's a lot you can do in 24 hours" and proceeded to say that he's going to do a "close re-reading" of the manifesto, which he reported to have read many years prior, but I could be getting confused here.)
Bruh.
You don't read The Communist Manifesto because you're a fraud and a charlatan.
I don't read The Communist Manifesto because it's a rushed pamphlet drafted with the intent to inform the demands of the European masses during the revolutions of 1848 and as such it holds very little value as theory.
We are not the same.
