IndyRef2, mandate or not?

Three arguments here, that either a) you need an overall SNP majority, b) you need an overall majority in the popular vote, or c) you need an overall parliamentary majority of pro-independence parties. #SP21

The first one seems to be the unionist argument (although I'm sure any mandate would have been rejected regardless). This is based on the basic FPTP system of winner takes all. That's fine, but we have a PR system in Scotland, so those rules don't apply. #SP21

But in reality, if that was the judgement, then the SNP have romped home in FPTP and there is a clear majority of those seats. This argument essentially ignores Green seats as important. #SP21

What about popular vote majority? Well that only works as an argument if apply the same logic to Westminster, which means no mandate for Brexit, not even under Boris Johnson's 2019 victory and certainly not under Cameron's 2015 pledge for an EU referendum. #SP21

The final route to a mandate is a parliamentary majority. Either this is, like in Westminster, the equivalent to a mandate for whatever policies have been put forward, or you may as well ditch parliamentary democracy as a representative system. #SP21

Both the SNP and Scottish Greens stood on a platform for indyref2, and they will hold a majority after today

Even if you don't think that is a mandate, there is absolutely no mandate for no IndyRef2, given all unionist parties fail to meet any of the three above conditions #SP21

You can either accept parliamentary democracy as valid, or continue basing your arguments on a flawed approach to 'majority', winner-takes-all politics based on FPTP, on which the SNP is a clear winner should Holyrood simply be a FPTP system. #SP21

Should clarify what I mean here, as in 2016 pro-union parties did win more than 50% of popular vote (which is on a knife-edge this year).

Popular vote on works as the basis for a mandate if it applies across the board. https://twitter.com/conor_matchett/status/1390957083147874304?s=20

Tories can't claim popular vote is what counts in Scotland while pushing through similar constitutional change based on less than that with Brexit which they believed had a mandate due to a parliamentary majority. #SP21

Of course, Boris Johnson could just say no. That hurdle is yet to be overcome by any pro-indy party and may require a trip through the courts to get a judgement on whether that position is sustainable #SP21
