The attention span of a toddler. The memory so empty he can't remember from one day to the next what he believes. But he's angry. And wants you angry, too. You might not notice then, he just might be outright lying.
The vulgarian's memory is the thing most suspect about him. One minute for a war, the next minute against one. And now, we get to see the results when that kind of mind has access to the most powerful weapons ever made. Oh joy!
Some guy with a degree in examining heads has said that the vulgarian has the emotional maturity of a three year old. Really? You think it's that far along?
The vulgarian thinks the rules don't apply to him. So what if every nominee in the modern era have revealed their tax returns, not Donald, not now. Do you know what's in those documents? Loads of excuses I'm betting.
