I'm not suggesting or advocating that you vote any of their candidates, either here in the West Country or anywhere else in the UK - I'd be the last person to tell anyone what to do or think - but I am suggesting that it merits further investigation on yours - and my - part. Their policies are generally self-evident - fairly left-leaning, liberal, eco-centric: all stuff that ticks boxes with myself and many of you - but what's worth considering is that the Euro Elections use Proportional Representation, so it wouldn't take too big a swing to get more UK Green MEPs into play. It might be worth considering, especially as quite a few people are either voting UKIP or not bothering at all "as a protest".
What I suggest is that - since they've included their email addresses - you write to the candidates and ask them how they intend to represent you in Europe - what they intend to do for your area and figure out how it differs from the other parties. If they are the people I hope they are, then they should respond...
You should also consider doing this for the other traditional Big Three parties. Their candidates' email addresses should be readily available / in the public domain - if they are not, or if they are unable or unwilling to address your questions and concerns, then they are not deserving of your vote.
Here's the current state of play. I live in South Somerset, so I'm keen, for example, to find out what Graham Watson did (how he voted / lobbied / worked (if at all) to pre-emptively prevent the recent flooding in Somerset - his leaflet said he was the first to call for intervention, but I think this was after the fact, not before. The region flooded badly last year as well, so there was plenty of warning this time round and I'm curious how he might have acted in that period between the two floods... if I find out and it turns out the Greens have been more vocal, then, well...)
I'm also looking at the UK Pirate Party.
