Here is a basic explanaation of how and when Trump has to pay his three civil losses:
He’s now on the hook for nearly a half-billion dollars across three civil cases. These are the rules for when and how he must pay.

Trump claimed in a deposition that he had in excess of $400 million in cash, which if true would still not be enough to pay his debts. It would be difficult for him to use political money to pay personal fines due to campaign laws. He is facing more legal costs in the criminal cases and there is a question whether his base is willing to donate money just to pay lawyers. His fund raising is slowing down, and his base might be thinking he is a lost cause.
In any event it seems likely he will have to sell assets, or use them as collateral for loans (which would be dumb since it will only cost more in the long run). Buyers know he is desperate and can get fire sale deals. Anyone willing to loan him money will surely demand high interent due to the risk of him unable to generate income.
What I will be looking at the next few weeks is if Trump is successful in squeezing money from his base. Historically there is a spike in fund raising after bad news. The difference here is that this isn't an indictment or arrest which could see him get out of it, this is a loss with a huge price tag. Will his followers really want to sacrifice their bank accounts just to pay for his losses?
