I've never understood the psychology of these things. Whatever the country and whatever the politics, the politicians always seem to predict that they will do better than they actually think they will.

I'd have thought that what you'd do would be the other way round - that you'd say you were doing worse than you thought you were, to try to scare your own people into going out and voting, while lulling the others into thinking it's already won, so why bother. But it never seems to work that way.
