Surely The Donald personally knows 66-1/2 billionaires. Trump won't kick in himself because he is a well-known cheapskate. But since he tells us he is such a great dealmaker/negotiator why doesn't he convince 66-1/2 of the other biillionaires to kick in a billion and change each to fund the wall? Write it off on their tax returns. Be a patriotic American. Wear a Hat or Pin that says "I KICKED IN A BILLION BUCKS FOR THE WALL". Everyone wins. What's wrong with that?
