Developers, much like movie producers, often have failures they write off with bankruptcies. Not every development is a success. Taking risks like that is a sign of a good leader, while a poor one never takes chances or risks.
The difference between Trump and Biden in that respect is, Trump put his money on the line to develop those casinos and ate the loss when they failed. Biden put taxpayer money on the line to do stupid shit like nationwide EV charging stations to tune of tens of billions and completely fucked that program away. Biden's lost far more taxpayer money on stupidity than Trump ever lost of his own invested cash.
I'd say once again, Biden is the bigger failure mainly because he has always been a fucking idiot.
