I got news for the Bernbots, Crazy Bernie's spent that money and whatever is leftover goes toward zeroing out his debt.
I think that you are on the right track. But like Ted Cruz transferred $500K to Carly Fiorina’s campaign after she had suspended her efforts, you can bet that the price for Bernie’s cave and subsequent support for Hillary was HIS campaign debt. Oh, and BTW, Bernie needs a personal plane to carry him from place to place while the general election campaigning is going on.
