2) If everyone who doesn't normally vote (over 33% of Northern Ireland, for example) decided to spoil their vote, instead, it would send out one hell of a message.
The only problem here is that a spoilt ballot paper could mean the voter is sending a message, but equally it could mean the voter is an incompetent tit. For that reason, I remain in favour of at least the option of 'None of the Above', but preferably 'Round them Up, Shoot them All'.
As a more general comment, perhaps it would be wiser of we kept our specific voting intentions to ourselves. For example, I consider UKIP to be a sickening bunch of filthy, small-minded, pig-ignorant racist bastards, intent on stirring up hostility and bigotry at every opportunity, and frankly no better than the BNP. I really don't need to know who here is planning on voting for them.
As another general comment,
this will end in flames.
