The way I see it, even the most fanatical Green Party voter would accept that there is no way they will get into power in this election, or any in the near future. Yes, they do have some pretty extreme and unrealistic policies, but for me there are also some very important and sensible policies they have about matters that no other parties are taking seriously. Would I want them in a majority government? As they are currently, probably not. But do I think having a handful of Green Party MPs will be beneficial to our government, making a stand for some of the (what I think are) important issues and providing some balance to the UKIP MP's? Yes. I don't really feel any strong preference to any of the other parties and their policies, and since I live in a constituency where they have a small, but decent chance of being voted in, with a candidate who appears to be quite down to earth and genuine, the Greens will probably be getting my vote.
