Like in party politics, the option with the most votes would be the winner. For example...
Red party = 50 votes
Blue party = 50 votes
Yellow party = 49 votes
Green party = 51 votes
The winner here is Green, but only 25.5% of people are in favour of them. 74.5% are in favour of NOT Green - but do they win ? The only way it would work is if 2 parties worked together to form a coalition of voters and vote for the same thing, forming a majority and overall control of the outcome. But that would be silly.
