I've namechanged for this as I don't want to be outed/stalked etc, but I am a regular and I've been following this thread with interest.
Swedes said "I think if you are truly left wing, in the old sense, you need to vote [Lib Dem or] Green."
Bang on the nail there Swedes - I come from a family of major Trade Union/Old Labour activists, and could never have imagined voting anything but Labour.
I started to have my doubts around the time they ditched Clause Four... but like any sane person I voted Labour in 1997 and was thrilled to see the back of the vile Tories.
However, the way Ken Livingstone was treated in the run-up to the London Mayoral elections in 2000 just compounded my unease , and the war on Iraq was really the last straw. Coupled with my emerging consciousness about the havoc we are wreaking on the planet, by 2004 it was clear to me that the only way forward (certainly in terms of formal politics) was to join the Greens.
I am lucky to live in Brighton - as noddyholder observes, a Green vote in my neck of the woods isn't wasted: we have 12 local councillors (holding a quarter of the seats on the council), and we look likely to return Caroline Lucas MEP as Westminster's first Green MP whenever Gordon decides to call the general election.
So if you live in Brighton Pavilion and can't be arsed with NuLabour or VileTories, please vote Green and make history. Similarly, if you live in Norwich South, Oxford East, or Lewisham Deptford, the odds are good too - and your Green vote will count, if not in 2010 then certainly in 2014/15 (remember Keir Hardie).
Quattrocento and ladylush - I'm so sorry you feel your Green votes are wasted. I could embark on a polemic regarding our retarded, medieval 'first past the post' electoral system... but I won't.
Suffice to say that, given the electoral strictures we have to work under for now, some local Green parties are frankly fucking lazy, and are strangers to the tried and tested methods of door-knocking and leafleting (Manchester Green Party, I'm looking at you).
But all it takes is a handful of dedicated activists to get out there and give the system a boot up the arse, so why not get involved and try and change things?
Finally (sorry this is long, but hey, it is a PartyPoliticalBroadcast) - if you live in London, the South East, or the North West, please please consider voting Green on June 4th in the Euros purely to thwart the BNP - who regrettably pose a very real threat and might just gain their first MEP in one of these regions ).
I'd hope that (regardless of any allegiance to Labour, Tories etc) we would all agree that there should be no platform for Fascists.
Plus our policies rock, and (just to prove we're not all humourless sandal-wearing bearded twats) funnyman Mark Thomas thinks voting Green is the way to go.
