There are times in all of our lives when we have to "do the right thing" and sacrifice our own personal interests for the good of others. This is extremely hard to do for anyone, but is the ultimate test of our character. I believe Donald Trump is at this crossroads today, and I am sure he knows in his heart that what I am about to say is the truth.
Short of a miracle, Trump does not have a viable path to winning the presidential election. He also knows that the consequences of a loss will change the nation in a way that perhaps a majority of Americans do not want to see it changed. Therefore, he needs to step aside before Labor Day so that this election can still be won by a right of center, more mainstream Republican ticket.
If you are reading this, Mr., Trump, you are likely recoiling and saying something unprintable, pretending that you can still win. You know as well as I do - or any successful businessman does - that a sale can be lost in the first impression. Clearly you had the right message for this "change" election, and you were in the right place at the right time to make the sale to the American public.
