The Out side will not have a problem in getting their Out vote out.
The In side will have some difficulty in getting their In vote out to vote In.
If the In vote does not get out in sufficient numbers then the Out vote will be more likely to outvote the In vote.
If you are minded to be In then you need to get out to vote In.
On the day, Thursday 23 June.
If you are not in when the canvasser calls you will be marked as out.
If you are in, but are for Out then you will be marked as Out even though you were in.
Is that clear?
