Why? For starters, because as you pointed out Trump isn't a career politician, like your old, corrupt, rich, demented pedo heroes.
You had a point right up to where you wrote " demented pedo heroes" which seems, irrelevant, over-the-top and unnecessary. Old, rich, corrupt career politicians says enough all on its own.
You are right, Trump isn't a career politician. In fact, he's not a politician at all. And it is unlikely he'll ever be one, even had he chosen to make it his career.
One last thing, why is it that folks so often assign ownership where that hasn't been established. These other politicians you've trashed aren't mine. Mine is someone much younger and fresher. Someone with new ideas consistent with what most people want today (and this means more than just someone different).
