TOBW is left wing and will always vote left wing. He's not as open minded as his criticism suggests. anyone who says they could never vote for one particular party really isn't in any position to criticise anyone else.
parties ebb and flow in their policies. if the BNP revisited their policies regarding bigotry and hatred, and became more mainstream, then I'd consider voting for them based on their manifesto. But just to be clear, their current outlook doesn't resonate with me.
