Not as far as politics goes.
Selling access to the White House can do only one thing--backfire. History has proven beyond any measure of doubt that the more you auction off entrée to the seat of power, that very power weakens as each favor is fulfilled. It compromises power to the point of submission. By the time the office-holder (in this case, the president) has advertised that anyone with the price of admission can expect their request to be granted, respect has long gone. That price of admission is the price of power--yours, and you've sold it for a bowl of soup.
Somebody out there is asking, "what has power to do with soup?" A fair question for those who are not familiar with the story of Jacob and Esau, but to condense it into one sentence: Esau was starving when he came in from the field and so intent on self that he sold his birthright for something to eat. Genesis 24:29-34
