Since when does a seat majority equate to a percentage majority - the type of majority required to win a referendum?
They achieved it (just) in 2015 but were then tied by the 2014 referendum result.
Since when does it need to, or matter, or is in any way relevant?
fyi, in 2016 snp has 46.5 % and greens 6.6%, both promoted independence, so thats a majority 'percentage ' vote. NOT that i'm in any way suggesting that matters as such or represents a given conclusion that automatically translates to a desire for independence.
