There is the theory that his very lack of discernible personality allows people to project whatever they want onto him. This whole 'he cares' stuff is bizarre, though. This is a man who nurtures anti-semites, supports terrorists and baldly refuses to condemn a Venezuelan president who is currently murdering his own people while being condemned by Amnesty and the UN. But despite all this, you get the same old guff about him 'caring' coming out.
It's all bloody odd, I must say. A madness seems to have descended on politics.
