Overall progressive anti-austerity politics needs the SNP to beat Labour in Scotland and that is clearly happening. It is going to be a landslide. But we also need the Greens to make a strong showing in key constituencies to build for a strong presence of sensible radical politics in Holyrood in 2016. Edinburgh East is THE key Green target seat. Voting Green rather than SNP here is crucial to build towards the Greens providing the radical spine to the SNP post-2016, just as we hope the SNP will provide that spine to Labour post-2015.
