There is a fairer system:
When you get to university, Molly, (if not before) you'll discover 'STV'. ("Single transferable voting") It's the system which student unions (and other enlightened bodies) have used for elections for many decades.
Under STV, no candidate can win until he/she has secured over 50% of the vote. STV works because voters have to indicate their first choice, second choice, third choice, etc of candidates. (i.e. you number them 1, 2, 3, . . .as far down as you want - You don't need to number them all if you don't want to).
Let's suppose that there are 6 candidates but, when the results are initially declared, the 'front runner' hasn't got over 50% of the votes. It's obvious that the person in 6th place isn't very popular, so his/her votes are redistributed. (i.e. the election officials look at who appears at 'Number 2' on those voting papers and adds those votes to those of the appropriate candidates.
If that still doesn't produce an outright winner (with over 50% of the votes), the votes of the person currently in 5th place are redistributed, and so on.
