IN AN ideal world, elections should be two things: free and
fair. Every adult, with a few sensible exceptions, should be
able to vote for a candidate of their choice, and each single
vote should be worth the same. Ensuring a free vote is a matter
for the law. Making elections fair is more a matter for
mathematicians. They have been studying voting systems for
hundreds of years, looking for sources of bias that distort the
value of individual votes, and ways to avoid them. Along the
way, they have turned up many paradoxes and surprises. What they
have not done is come up with the answer. With good reason: it
probably doesn't exist. link Let's hear from Winston Churchill:
“It has been said that democracy is the worst form of government
except all the others that have been tried.”
