The guy has accomplished the extraordinary, and it's easy for loads of people to see that as some sort of intentional, purposeful brilliance.
But I just don't see it.
Instead I see someone who just breaks people's brains. People cannot comprehend someone that immoral, who lies so effortless with every word, and so utterly shameless. They just can't. So when Trump declares that he's going to cut trillions from government spending and eliminate the deficit and pay off the debt, it's impossible for many people to understand that he has no fucking idea what he's talking about, and the little bit he does understand he simply lies about.
Like I keep seeing articles from left wing sources talking about Trump being "humiliated". Trump is utterly incapable of humiliation. When caught in the most outrageous lie, he redoubles on it, which again, tens of millions of people just cannot comprehend someone so utterly immoral and busted, so immediately they think "oh okay...I guess somehow he must be right? I mean, no functioning human could lie so egregiously".
He is so thoroughly a garbage human that many are caught out by him.
