You are right, at least sort of.
The thing is, Donald Trump is the sort of guy who has, all of his life, lived on the margin of the law. Admit it. On a personal level, the guy is pond scum. Right? I mean....Trump University? Can you try to defend the indefensible there? He tiptoes around the law, always trying to stay on the right side of it, and frequently succeeding, with so far only an occasional, or not so occasional, civil suit where he got caught.
In order to do that, you have to have lawyers who are willing to play along, and Trump knew that. And the same sort of lawyers who will go along with those barely legal schemes, and we know that Donald Trump likes a lot of things that are barely legal, are the sorts of guys who would try their own barely legal, or even "it's only illegal if they catch you", schemes. That's the sort of guy Michael Cohen was, and Donald Trump knew it.
So, he almost certainly did not know the details of Mr. Cohen's tax evasion, but he knew that Cohen was the sort that would find a way to get around paying taxes by any means necessary.
What's happening right now is that there are a whole lot of people (i.e. Democrats) who have a very powerful incentive to look at everything The Donald has ever done and find somewhere that he stepped onto the wrong side of the line. I don't know whether or not they'll find one, or if they do, whether they will be able to turn that into impeachment, but they'll keep looking. So far, they don't have it, but they'll keep looking.
And even if they don't find that impeachable offense, in the course of it, what they will show is that Donald Trump wasn't exactly the sort of successful businessman he claimed to be. Instead, more of them will see that he's the sort of successful businessman whose success came out of screwing everyone he could, and throwing partners under the bus when they, like Michael Cohen, were not longer useful.
A lot of people thing he's a good president, and in some cases, they have very strong arguments, but on a personal level, wouldn't you agree that this is one really bad hombre?
Answer honestly.
Minor correction. There is no reason to think that Trump minded about the legality, just about whether he'd get caught. And being narcissistic, and surrounded by yes men (and I do mean men) for most of his life, his assessment of his own cunning has grown.
