@hightor,
I had not read this before, but I have just finished reading it now.
My impressions are the article is a lengthy rationalization of a preconceived position.
We've heard little but accusations of "collusion" from Democrats the MSM for over two years. The article correctly points out that collusion is not a meaningful legal term, and that, while collusion of sorts may have occurred, it (reluctantly) acknowledges that no compelling evidence of criminal conspiracy was found.
The article states that as a matter of (unproven) fact that there is undeniable and ample evidence of a Russian effort to tilt the 2016 election towards Trump. I find that contrary to both the facts, and Putin's likely motivations & self-interest.
In the first place, I don't know of any systematic bias in the typical Russian efforts to sow public discord and mistrust in our country. In addition, there is a significant likelihood that much of their activity was anti-Trump. It is highly likely that Russian Intelligence services were, from the start, well aware of Steele's ongoing for hire investigative services while he lived and worked in Russia, and also of the sources he dug up for the anti Trump dossier he produced for and sold to the Clinton Campaign. How could they have allowed that if they were so interested in a Trump Victory ?
In the second place, from the Clinton "reset button" for our Russian relations, to the Clinton-enabled sale to Russians of North American Uranium Production sources, Clinton had facilitated Putin's interests rather consistently.. In stark contrast Trump's announced intention to make the U.S. a net exporter of Petroleum and natural gas was a direct and immediate threat to the principal source of income for a weak Russian economy.
I was a bit confused by the article's inconsistent and misleading treatment of the Obstruction issue. It first notes (correctly) that The President can be removed only by Impeachment by Congress and that no unrelated criminal action should take its place in that area. However it also ignores the President's continuing authority and responsibility to run the Executive Department and implies that Trump's amply justified dismissal of the FBI Director (recommended by the acting AG) was itself necessarily an act of obstruction. Lastly there is no clear evidence in the Mueller Report that the investigation found sufficient probable cause evidence for criminal obstruction. Mueller's duty was to find and report evidence warranting criminal action of any sort - something he did relentlessly with several witnesses in the investigation. However, despite this, the article asserts, without evidence, that Mueller indeed found sufficient evidence of criminal obstruction but chose to refrain from reporting a legal conclusion in the report, presumably out off a high minded regard for the Constitution. That proposition both inconsistent Mueller's behavior in the investigation and a bit hard to buy.
