Psychiatry has tons of syndromes to describe unexplained behavior, but one I think needs to be added is "Ass Clown Syndrome" (ACS). What is this? It's the illogical belief someone that is exceedingly stupid will make a fine leader. How they arrive at this belief is unexplainable, but it's real.
In Texas we have a man named Robert Francis O'Rourke that goes by the name Beto. He's stupid...exceedingly stupid, and has few (if any) redeeming qualities. He makes stupid statements, backtracks on the statement, reinstates his belief in the statement, and in brazing stupidity, doesn't remove himself from the public eye even when there are pictures of his drunken self proudly showing he pissed his pants. Nevertheless, people voted for him, which is unexplainable except those that did are suffering from ACS.
I have relatives with a good education, can only be described as very bright, were raised by respectable parents, and still voted for Beto. They love him, which made me scratch my head, until I realized they were suffering from ACS. It's a terrible thing, and as far as I can tell, it's untreatable. It's a modern tragedy, but maybe a cure will be found in the future. We can only hope.
