This shows how Trump has gone downhill real fast. This spoiled brat of an Orangutan has really shown his true colours in the last 10 months or so.
I don't think any person in the history of the world has had a mental deterioration in such record time. It's actually pretty sad. The economy was running like a well oiled machine. But when the pandemic hit, his mental capacity was exposed and proved he had no leadership skills whatsoever. Then the election campaign started, and things went from bad to worse.
A lot can change in four years. People change, and sometimes not for the better. A person starting a Presidency is very rarely the same person leaving a Presidency, especially if he's in his mid 70's. Trump is nearly 75 years old, and not in tip top shape. His mind could be deteriorating faster than his body.
Look at what happened to Ronald Reagan. Overall he was a nice guy, but he really struggled in his last couple of years of office, with his dementia and memory loss kicking in. Father time is gonna get you sooner or later. Maybe the same thing is happening to Trump. Some people age faster than others. That's just the way it goes sometimes.
