Sunset from #LBI

According to The Center of Responsive Politics, Donald Trump has over $22 Million cash on hand. So far, in the general election cycle, he hasn’t spent any money on TV ads or anything else to broaden his message to the general election public.
He received, in kind, according to various sources, over $2 Billion in free advertising during the primary season. He continues to call into various news shows, mainly on Fox, to get his message across. He is only ‘preaching to the choir’ by going on various Fox shows. There is nothing wrong with that, but everyone knows that he can’t win the general election by reinforcing his views with his followers. He has to go out and get people who either don’t know him, or win over people who haven’t supported him in the past.
He hasn’t had any media buys for the future that I am aware of, so why is he hoarding his cash? Three possibilities come to mind:
I think options 3 and 4 are the most likely. Option 3 would allow him to funnel the money back to his family. And if he is holding out for option 4 this is going to get really ugly!
Spent the weekend at Tanglewood watching my nephew, Will, play at the Boston University Tanglewood Institute.
