I also think your (now flagged) parent comment is mistaken, in that, I, personally, don't know it's a witch hunt and total fabrication. Is it possible that there's no there there? Well, yes. But, is it certain? Of course not. Is it even unlikely? I'd give it 50/50 odds.
Can I imagine that if approached via some tangential proxy for Russia or Wikileaks, that Trump, or someone in his campaign might have agreed that hacking Clinton, or releasing her campaign's emails was a good idea -- given my impression of his disregard for norms and desire for mischief, and a win at all costs, I can totally see him saying go for it, without considering the consequences. He was definitely knowingly underhanded throughout.
So, I don't doubt if he'd had the opportunity that he would take it, thinking he's immune to all consequences. But, then I'd have to wonder if the Russians would really approach him. That's where my doubt comes in. But, given his shocking and irrational fawning over Russia, the financial and other ties several of his campaign aids to Russia, maybe. That he publically asked for hacks Clinton's emails didn't help optics.
Maybe all his evasions and bizarre behaviors are to compensate for his insecurities about his net-worth, and not winning a popular majority, and his macho man-crush on dictators, and his want to be seen as strong as they.
But his historic lack of transparency is what's feeding the "conspiracy" more than anything else. He could probably put all this to bed instantly, but not while protecting his fragile ego.
