Who is this mystery political opponent and what were that allegations? Are you talking about Hillary? Are you actually arguing that Hillary set this whole thing up, leading right to Cohen's doorstep? Amazing that she couldn't stop Comey from breaking protocol to hand Trump the election, given how omnipotent she was and still is.
What's even crazier is the Trump explicitly behaves the way you describe. Trump has openly alleged crimes by his political opponents. "Lock her up!".
This is what scares me. You are so afraid of being wrong about Trump that you latch onto whatever makes you seem right. A lot of Americans (probably the same amount that think we've never landed on the moon) are in the same boat as you. It's disturbing.
Just to be clear, I don't have any money on collusion or no collusion. I have no idea, and I've said before that my hunch is that it didn't happen. However, I don't have any reason to believe that anything done in this investigation was improper, at least in any substantive way (manufactured evidence, destroyed evidence, improper warrants, etc.) I don't care if you are right or wrong on Trump. But you are so deeply invested in his defense you aren't seeing clearly anymore.
