No political party perfectly matches my wishes but the closest are the Greens and they will be getting my vote next week. I do not see this as a wasted vote at all, rather a chance to say how I feel about many matters.
UKIP may pick up some protest votes but I want to vote for a real party with real policies. UKIP seem to be strong on getting out of Europe but very little else. The Green manifesto looks well thought out. They have changed. Make up your own mind.
Use your vote next week.
The Greens - a wise choice.
