Some may ask “Where is the birth certificate?”. I question if he ever received a high school diploma.
He just didn't earn it. Or his college degree. Or his law degree. Or his seat in the Senate. Or the Presidency.
This little man has been socially promoted his entire life, up to and including his current position.
Of course, it hurts him in the end, because his native abilities (whatever they may be) were never developed. Of course, it hurts us all too.
