In their September 1 issue Maclean's quotes Elizabeth May as saying she is confident that David Suzuki will run for the Greens in the next election [link].  That would certainly be a coup of the highest order, and if anyone can pull it off I think it would be Elizabeth (she is a close friend of his).  My understanding is that David has been repeatedly asked by various Green Parties to run for office and has always declined.  David was the keynote speaker at our 2004 General Meeting in Bragg Creek, Alberta (near Calgary) and brought down the house with an inspirational speech.  David - Please tell us now is the time you will take this next step!
