I just took a quick glance at the official positions of the Greens and PCs, and I have to say you're right about the Greens being somewhat focussed on teh environment, but they do branch out into agriculture, resource-exploitation and education policies too. Surprisingly though, the PC website has almost no party platform whatsoever, just an e-mail to share our ideas. So I suppose this is all the more reason to get to ignore party affiliation and vote candidate. I know many PCs have supported the voucher system in the past, and who knows, there might even be other candidates from whatever party out there that will have some good ideas too.
