is the general electorate actually as sensible as you are?
If you have to go by what people give you as reasons to vote one way or the other, you almost have to conclude that a large section of the electorate doesn't vote rationally. It's anybody's guess as to how to translate 'rational' into 'sensible'. Combined with the (increasing?) influence on voters of ambient impressions down to the last minute, this makes it difficult to predict election outcomes.
