Running for president to get "more money" would be an extremely dumb strategy for someone who's already a multibillionaire. Dumb people do not win presidential elections, especially not with half the funds and with the entire propaganda machine shitting on them non-stop for months. He could have just kicked back and enjoyed his fame, like he did before he announced he's running.
He ran because he got free press, which meant free marketing for his books, which meant free money. Also campaign donations are basically free gifts of money to someone like this. He even called his transition team money 'my money' to Chris Christy (Michael Lewis' book which is a very good read).
His inauguration party alone rented out his own $5k ballroom for $150k. He rented his own offices for triple their cost to his campaign. The list goes on and on until you realize it isn't here or there, but all the time, non stop that these grifts are happening.
The bill for golf playing is over $100 million. His super bowl party alone was $3.5 million and even though it was on the official schedule a reporter asking about it was berated for implying 'that the president wasn't always working'.
Once he leaves office the rest of his life will be lived in court.
You can't rent out "just" a ballroom for an inauguration, or anything or anywhere ab president does or goes... The amount of security and extra amenities that go into an event that big certainly add on. I don't know whether it balances or not, but this strikes me as absurd.
That wouldn't be payed for by the campaign though. No one said he rented 'just a ballroom', you came up with that on your own. The hotel charged his campaign $150k for the ballroom that they usually charge $5k for.
The security extra is where the $100 million in golf comes from. Local police security is also why his campaign owes millions to the cities he has used to hold rallies and refused to pay.
