I think most of his ignorance comes from a total lack of interest, in anything that does not directly involve him. That’s due to his narcissism, and his ego. And of course very low intelligence.
He thinks he is the best at everything. Why would he need to learn anything?
And another Forbes article:
Wait, does that mean when he says he never met someone, he’s actually (in his mind) behing honest?
But he always does remember the coffee.
…but they’ll vote for him anyway because he’ll lower their taxes.
Convict Donald waving to nobody again;
Yet again, you’re posting a video about nothing. We literally can’t see what or who he’s waving to. This post is useless. If the camera swung around to show what he was waving to that would be one thing, otherwise it’s just, “Trust me there was nobody over there.” Might as well not even bother with a video because it’s literally a video of Trump waving.
The only people allowed on the tarmac are his own crew and the Secret Service detail assigned to him.
We know that with 100% certainty? Seems like an assumption.
We have so many videos showing Trump legitimately being confused. Why do we need a video that’s not showing anything?
The “Trump is waving at nobody” almost seems like a joke meme at this point rather than anything legitimate.
You’d think that if there was a crowd there, the cameraman who’s being paid by Trump to record this would show them.
Forming granting mass finger…???
Well now, is Trump confused or is this something he staged to make it look like he has a crowd? If this is a cameraman that’s trying to put a puff video together. In which case that doesn’t even apply to the topic.
Again, this video doesn’t mean anything.
Now that video from @griffin1977, LOL that shows a confused Trump. 
Oh, there’s more where that came from;
“Joe Bride is the worst… he will be a fading nightmare, a fading, I have a fading memory (emphasis mine), but do you mind if I change it?”
Sometimes Trump gives me Bobby Newport vibes.
Okay, that is a tough name, to be fair.
Right afterward Trump was heard to remark, “Yeah you know Big Bird’s best friend. Nobody knew Big Bird had a friend before, he was very shy you know…”
To paraphrase John Wayne in She Wore a Yellow Ribbon: “It’s a hard name to pronounce. It’s harder if you’re stupid”.
True, but if Biden stumbled over it, I’d give him a pass.
Not really. It sounds like it’s spelled.
