Right...And that one was quite the stumblin'-bumblin' piece of work, too....Nothing at all like his teleprompter jobs.
You asked for evidence that he didn't write his "autobiographies"?...There it is.
So you don't have any evidence to support that claim. Not a shock.
The evidence is in the language.
Neither of the two books use the kinds of similar metaphors and analogies you'd expect from the same author. Moreover, if little Barry's writing has proved anything, it's that he has no concept for the usage of overall thematic structures.
If he can't even put together a tight 20-minute speech when he sequesters himself for days on end, there's zero chance that he can write an entire book.
Anyways, most books like this are ghost written...What's so hard to believe that Barry the Manchild's are any exception?
