You trust Fine Gael, Labour, Fianna Fail more that the Greens? The other parties have been running local and national government of this country for the long term. If we had Green policy where government appointments were made to qualified people and not to friends we would have been better off in banking regulation and other areas.
From listening closely to politicians the Greens and especially Eamon Ryan are the most honest. They always explained what they were doing. They had to go into government to show they were not irrelevant as they were always dismissed as before. They didn't go out of government earlier where they might have gotten some credit for it but when it might have made the situation worse.
Unfortunately being honest doesn't look or sound as good on media as is finding the latest most popular ideas and expounding on them dramatically.
Other parties and independants pick up green issues because they're fashionable and think they'll get votes for it (and they do!). It's okay seeing good policy picked up but cringe factor is a bit too high at times when it is being implemented by eejits who have latched onto green fashion but not principles. :-7
