I see the Greens as a sort of political tool. A large support for the Greens would, hopefully, kick Labour into touch and do for them what UKIP has done for the Conservatives- get them closer to their core values.
However, while I support the general Green ethos I’ll not be voting for them next time round. First we need a party that has at least a nod to left wing reasonableness rather than right wing selfishness in government. The Conservatives will probably get further right wing given the upswell in support for UKIP and may well win the next election. For me as a lefty voting Labour in the next election is the way to start reeling in the Conservatives, then when Labour are in power safely I’ll probably switch to Green. If there is a large amount of support for the Greens while Labour is in power my hope is that this will make Labour more left wing.
The likelihood of all that happening, I realise, is slim, since apparently immigrants and polar bears are all utter bastards according to the bulk of the voting public.
I also have major issues with the Green’s lack of support for nuclear power, the short term answer for a lot of the environment’s problems until an alternative is found, and their stance of a lot of scientific research is very backward.
