First of all, and you probably know this, collusion isn’t a legal term. You’ve never seen me accuse Trump of this and I wish the media would stop.
“coordination”—a defined term—in a counter-intel investigation, and (colloquial) “collusion” in a criminal case, are different.
There is conclusive proof of collusion everywhere you look, that’s not really the issue. Colluding in itself isn’t a crime that I’m aware of. What matters is who knew what and when.
Establishing Mens Rea (the intention or knowledge of wrongdoing) is what’s important. Aiding and Abetting a crime, obstruction, financial crimes…These are crimes.
So yes, despite your claims, from a legal standpoint, the issue isn’t “collusion”, but the state of mind of those that were colluding, what they know and what their intentions were.
So the question is, do we have conclusive proof that Trump or his associates committed crimes with respect to their collusion? No.
Should we expect that at this point that if there were crimes committed that we’d necessarily know about it? No.
Thus, we have lots of evidence of unusual activity but no specific evidence has been presented that either provide proof or fully exonerates the President.
I’m curious when Whitewater was being investigated and Mr. Star stumbled upon a certain intern performing sexual acts with the President, did you protest given that was outside the original investigation, was that a “witch hunt”?
Personally, I don’t think so.
If not, how does what Mr. Star uncovered about Clinton going to be any different than what Muller will uncover about Trump and his associates (and it will come out, I’ll put my money where my mouth is if you’re a betting man)?
