While the system is very complex in its internals... how you should vote can be very simply described.
You should list the politicians from most favoured to least favoured.
There are only two reasons why you should stop listing your candidates in order of your preference.
1. You've run out of spaces on the ballot.
2. ALL remaining candidates are *equally* distasteful to you. If there is one that is even slightly better in your opinion than the others, list that next on your list of preferences.
If you follow that recipe for voting your vote will go where you would wish it to in the circumstances.
Exactly what I've been saying throughout the thread, I just couldn't make it this concise. Thank you DeV!
but the vote had the potential to be left in any of the piles it was in,
im just confusing myself now
So in theory those 25 surplus votes could transfer to a candidate from the same party.
Alternatively, they could transfer to a few of the candidates least likely to succeed.
I think something like that does happen but it could still give the outcome I mentioned above.
End result could be a government partially elected by random selection!
