Where Greens are unavailable on constituency seats I recommend a vote for the SNP candidate.
If you are an SNP voter then regional seats are harder to gain when you have won constituency seats.
Since the SNP are likely to do so well this election a vote for Green on the regional vote will keep the SNP on the right track and show greater support for independence.
The Alba Party have done a great video to explain this, however I feel the Greens are a far better second vote.
