So you have no answer for my question?
Here, I will show you how answering works by answering yours.
The premise of your question is invalid as I HAVE discussed the possibility he is crooked. I think he’s routinely bent rules and laws. I think he’s routinely used the system to his best advantage.
I will take it further: let’s say, for the sake of a hypothetical argument, he called up Putin personally and said, “hey, Vlad, old buddy, I’m trying to beat Hillary Clinton. Got any dirt on her?” To this request, Putin sics his worst hacker team (as evidenced by the fact they left a trail of crumbs behind so huge as to be comical), who hacked the DNC and Podesta and leaked it all to Wikileaks. Assange goes out of his way to mislead us all by offering a reward for information on Seth Rich’s murder - going so far as to “accidentally” refer to Rich as his source - and releases the worst parts of the emails to the press. We find out that the DNC has so little confidence in their candidate they have to cheat to keep Sanders out. We find out about lies and cheating to make a whore blush. None of this is specifically denied by the principal parties.
In that worst case scenario, what did Trump do that is illegal?
