This isn't a party political observation but it is clear that Ken Livingstone's campaign has imploded.
I cannot remember another political campaign where so much has gone wrong.
Others have listed and discussed all the missteps, poor communication and failure to connect. Ken has been accused by his own side of hypocrisy.
What is surprising is that the one thing Ken was good at in the past was creating a winning narrative. All of that seems shot to pieces.
It is a lesson to all brands, communicators and politicians: never be complacent and always be attuned to how the public see you.
