Actually, each individual who votes plays only a microscopic part in the
result of the election. So you really can't fault people for the way they
vote; the amount of responsibility each one carries is vanishingly small.
In fact, maybe this is the problem - since people know that their
votes don't really matter, most don't worry much about how they vote.
You could almost see a democratic election as a system designed to
minimize personal responsibility for the outcome, and therefore to ensure
irresponsible results.
