That is a little vague. Some of his crimes only happened because he became a politician, so of course the prosecution would be seen as political in that sense. What I would like to know is which crimes did he commit that were only prosecuted because he was a politician, which would otherwise have been ignored?

But also, they probably should have happened were he not a politician. He's been committing fraud and other white collar crimes for quite a while. Unfortunately, we go far too easy on white collar crime in this country. And he's a master of plausible deniability, where he effectively asks other people to commit crimes on his behalf, but in a plausibly deniable way with no written trail.

His wife in the 1990s accused him of rape and intended to sue him as part of the divorce proceedings. She changed her words when she obtained a generous divorce settlement, moving from outright rape to "not in the criminal sense, I just felt violated".

That was over 20 years before Trump gained political relevance.

Your definition of political ("not happening if he wasn't a politician") is not what that definition is.
