Mike, no matter how much gloss you put on it, IF Boris is voted in by the membership he will have been 'voted in'. Brown wasn't, in spite of the fact that Labour Party rules state that the membership should vote. Brown was 'nodded through'. Democratic that.
You state that 'nobody voted for Boris and this situation is totally unprecedented in our history - however much you suggest otherwise.
As for 'pointing out facts' - Half of all Prime Ministers appointed in the last 100 years, were not appointed as a result of a General Election, ie voted in in accordance with party rules. Not exactly unprecedented. Not up to your usual standard Mike.
