First is, what possible reason could you have for voting for that bunch of closet racists and lying toerags? If you're going to engage in a protest vote, at least give it to someone who can't make much out of it. Sorry if that sounds a bit harsh, but I despise the tories with a passion, they care nothing for anyone earning less than about 50k/year, they have no understanding of poverty or unemployment or the benefits system. They don't understand state education or healthcare because they don't use it.
What I've noticed is how much emphasis the media of putting on the BNP, yes they're fascists but they won 13 seats, the Greens gained more than that and hardly get a mention. The media concentrating on the fascists just gives them more publicity and pushes their vote up.
