Child and all not withstanding..
He knew the IRS was after him for all of his crooked tax evasions and schemes flooding the loopholes in the tax laws beyond recognition and defraying the spirit of these laws to the point of going to prison and all of his business swindles and fake bankruptcies to go with it so he ran for President of the United States.
Offense being the best defense..
His back against the wall..
He also knows how gullible we humans can be..
He would have had to go bankrupt personally and go to prison for an extended period of time and lose his family and fame and everything he owned right down to the penny and that he could never do and repeat this success again.
So he ran for President.
