I have no idea why we still have such odd arrangements for governments. Regardless of what "democratic" nation you look at, instead of hiring people capable of doing a job we let people, based on their own personal beliefs and delusions, campaign for the job and then at least in the UK allow the person who gets less than half the votes from less than half the possible voters have what can be very important positions.
Seeing as politicians seem to forget what they are supposed to be doing, i.e what is best for all not what they think is best for a few, I don't know why they don't just do away with the whole system and start a fresh.
