That Trump is a liar, cheat, fraud, and conman isn't the "big reveal" in the NYT's series of articles; the amount of his indebtedness—private as well as business—is. That debt load, particularly the personal debt, makes him vulnerable to influence, both domestic and foreign and prior knowledge of that enormous debt load should/would have flagged him as a major national security risk. Which, by the way, we've seen but now it's confirmed.
I'm just a simple country girl but my thoughts are absent a requirement that candidates for the highest positions in government be subjected to security screenings, providing financials (including tax returns) for a specified period of time should be mandatory. For one thing, such a requirement would likely reduce the number of felonious individuals running for those offices. It has been claimed that this would be a violation of candidates' privacy. Well, yanno, they'd know that going in . . . so? And, really, who is naive enough to have any expectation of that level of privacy anymore?
