It's all unsubstantiated, honestly. I don't believe any of the rumors on either side, because both sides have a huge incentive to lie and insinuate bad things about the other. It's dirty politics 101, and the Clintons invented it (say what you want about them; but they are masters of dirty politics -- which you have to be to become president).

I judge them based on what they've said; and Hillary has offered up some good ideas and a whole lot of rhetoric while Trump has spouted inconsistent positions, many of which are frightening to me. Furthermore, when you do even a cursory bit of research on their statements, it becomes clear that Trump either doesn't know the truth or simply doesn't care. Add to that the ease with which Clinton manipulated him in the debates (she goaded him into a fight which plays well to his 30% base, but makes him look very unpresidential to the rest of the voter base). If Clinton could manipulate him so skillfully, how would he react to provocation elsewhere on the international stage?

Regardless of Trump's politics (which I happen to disagree with), he as a person has shown that he is unfit to hold public office at any level. He seems to have little regard for ethics and fair play -- his idea of "fair" is when everything goes in his favor, and everyone is conspiring against him when it doesn't. He is little more than a con-man reality TV star, while Clinton has lived a life of public service.
