My take is that IF (that’s a big if) Trump becomes president, then I don’t want him owing $500 million that makes him a target for bribes/blackmail/influence from enemies abroad. Not like he isn’t already and hasn’t already been influenced, but it would be worse. So if the GOP has to suck it up and pay those fees for the candidate they choose to be their guy, then I think it is in the country’s best interest to do so. Also, I’d rather they pay now than him trying to weasel out and have the federal government pay off his fines if he becomes president.
I would love nothing more than for him to go completely bankrupt (again) and lose the presidency and go to jail for the criminal charges and have his family be on the hook for all his debt. But maybe the GOP going bankrupt is a bright side.
