Yes. The 'No' campaign smacks of throwing the toys out of the cot for no reason other than venting. Sinn Fein's take on these issues is if they say 'Yes' we say 'No'.
I was talking to my folks the other week and my mother will be voting "no" and my dad will be voting "yes", so I told them just to not bother voting as it will just cancel each other out!
