Turns out, LOSER45 is a really grate righter:

[Leghorn21]

After having written many best selling books, and
somewhat priding myself on my ability to write, it should
be noted that the Fake News constantly likes to pour over
my tweets looking for a mistake. I capitalize certain words
only for emphasis, not b/c they should be capitalized!

1. It's "pore" over, not "pour," you illiterate twit.

[thegoose]

3. And bestselling or best-selling

In this usage. Moron.

[calimary]

9. And he doesn't write those books. Ghostwriters

like Tony Schwartz do. He hung around with His Orangemanship and took a lot of notes. Then he put it together in book form. So trump could stick his name on the front, which is about all trump is good at doing (besides lying and conning people, that is).

And that’s the REAL “Art of the Deal.”

[Sanity Claws]

7. I was just about to write that

He is an idiot.

[Solly Mack]

2. LMAO

4. O.M.G.

He's written many books? I'm feeling the spirit of a ghostwriter rising in the mist. The ghosty is jangling his chains, moaning, groaning . . .

There's no limit to this man's lying, egomaniacal spew.

Spare us all, Donnie. Pack up your hairpieces and resign.

16. I Can Picture Him Visited By The Ghost of Richard Nixon...

...who would just sigh, shake his head, and say, "Forget it; it's already way too late for you to avoid ending up even worse than me...."

5. Onlee thu beast spellur!

[Bleacher Creature]

6. Why exactly have we stopped talking about the 25th Amendment?? NT

[spanone]

8. 'somewhat priding myself on my ability to write'

yes, he's well known for his long historical dissertations

[smirkymonkey]

10. Has he actually ever written anything? He's borderline illiterate.

He's always had other people do it for him.

What is he talking about "priding myself on my ability to write"? He can barely construct a 140 word tweet without butchering the language. God, he's such a fucking idiot!

[smb]

17. "Borderline" Illiterate? Did He Take Classes To Improve To That Point? nt

[Croney]

11. His first sentence is grammatically incorrect.

The phrases "after having written" and "priding myself" require something else than "it should be noted." I used to know this stuff decades ago but I've forgotten the terms I'm looking for.

[UTUSN]

12. There's stuff that could be higher priority for him to obsess about:

1) The country;
2) his desperately precarious legal situation.

[dalton99a]

13. Ok, everyone can rest easy tonight knowing that the fate of the free world is in good hands

Fucking moron
