Mark Cuban, more billionary than Donald Trump, just challenged Trump to a debate for which he will pay $10,000,000! Cuban asked "what have you got to lose"? What does Trump have to lose?

I guess he will pay the big bucks to Trump. We all know how much money means to  Donald J. Trump don't we? Cuban owns the Dallas Mavericks basketball team and is an entrepreneur with a vast business empire and totally loaded money-wise.
