A "lot more" because you are confining the issue to KS poor judgement amd saying we were being hysterical for some reason. But actually we are talking about Peter Mandelson 's behaviour too which IMO is much more serious. KS is a lame duck now and irrelevant really in the long term scheme of things.
Re Profumo, it's the scandal that he was potentially passing on state secrets to Keeler who was also sleeping with a KGB agent. Mandelson has actually passed on market sensitive information to Epstein. So the first part has already echoed a past scandal. Not exactly but it echoes. It will be interesting to see what comes out re Epstein and what he did with that information.
