Wolves Students’ Union uses
Single Transferable Vote (STV) for multi-winner elections and
Alternative Vote (ATV) in single-winner elections. These are representation systems in which a person’s vote can be transferred to a second, third, fourth choice and so on (according to their stated preference) if their first choice is eliminated during the vote count.
If you want to understand more, have a look at Southampton’s explainer video for a STV election. The most important aspect of STV is that a voter ranks candidates in order of their preference so if you speak to a student who has already decided not to vote for you, convince them to make you their second choice – it could make all the difference when determining the result.
