PT Barnum was another showman- bigger for the time perhaps but he did often lie about his self promotions as this article says. 
What we really need to see is just who owns Mr. Trump so it's time to open his books as his most of his opposition has done for over a quarter century. There is so much speculation The Donald -like PT Barnum, is just hot air and gas besides being a Beast to women. 
So as they say Let's see the Beef! Open the Donald's Income Tax and see if he really is the scoundrel of fantasy.
