Stats table is missing "Don't know" or "Refused to answer" responses

This article has an error in the tables. It fails to include the number of voters who were "Don't know" or "Refused to answer". For the latest 1 News poll this was a massive 16%, so must be shown in the results table.

However, I'm a new Wikipedia user and don't want to mess it up. I also don't have the time to do it.

Cheers Geoff
