The European Elections 2004 are on June 10th. I've just finished looking through the various party manifesto's and have pretty well made up my mind to vote for the Green Party. Check out their manifesto. It makes the most sense to me (I'm not a member). I particularly like their stance to be part of Europe but to reject the single currency. Their policies seem well thought out.
The Lib Dems would be my second choice. Their manifesto is also quite good but a bit softer towards neo-liberalism. I'd probably vote for them in a National election. Can't say I trust the Conservatives or Labour Party any more and I think it's foolish to reject the European Union out right. We need to be at the table shaping the way Europe will work.
