No one had $100M in hats money. Bush had that much in soft money.
Well technically Donald Trump has $10 billion in hard money (or whatever his net worth is). Since it his personal fortune he has no restriction whatsoever on how he spends it, giving him far more discretion and leverage than any other candidate. The question is how much does he have easy access to (not tied up in Real Estate or long term investments) and how much would he be willing to spend?
