I think body language is important.
And like it or not, rightly or wrongly, jeremy Corbyn did give the impression of a laid back, perhaps not overcaring about much in life, sort of image. Even if his words were saying otherwise.
But equally, and I count myself among them, we can get fooled by a polished image.
I think that if someone likes what a person is saying, then yes, it doesnt matter too much what they look like and how they act.
But it strikes me, that there are more voters nowadays like me, who are willing to switch allegiance quite easily and quickly.
To my mind, for some time now, the parties themselves change. Especially if and when there is a new leader. Who then puts a new team in place.
