What constitutes "stellar"? The guy is worth $10 billion. Every entrepreneur has successes and failures. Some of the greatest and most wealthy have known defeat and failure and were able to recover.
The fact is that Trump has been successful in the private sector, domestically and privately, placing his money where his mouth is. He is not a first term senator (Cruz and Rubio) who have spent the vast majority of their lives feeding at the public trough. They are not the risk takers who have made this country what it is. He has created tens of thousands of jobs. The tax revenue gleaned from his efforts help pay for the government.
He wouldn't be worth anything close to that had he paid off his creditors. I agree that he legally stiffed them, but that doesn't make it right, to me. That also makes him less than stellar in my opinion.
