What, don't vote? Hats off to the SNP for decimating the opposition. There is no real choice in Scotland anymore for the majority of non-SNP voters. Labour are in pieces, Lib Dems have been annihilated, and, although I do vote Tory personally, there is a huge stigma attached to a Scottish Tory vote.
So realistically, if you oppose another referendum, who do you vote for? There isn't anyone, because the only other way is to vote tactically if you want to stop the SNP, and many just aren't prepared to vote for a party they don't want to vote for, just to stop a single policy from a party they might actually be inclined to vote for otherwise (mores the pity).
The problem is now that the SNP have around 50% of the Scottish vote. And whilst I don't really feel that is enough of a mandate for another referrendum, on account of the recent one results reflecting the will of the majority, and the SNP share of votes not being suitably higher than in, say, the last MSP election.
Next year will be telling though. If the SNP should get, say, 60%+ of the vote in the MSP elections, assuming another high turnout in elections, then I think there could be an argument for another referendum, assuming it is in their manifesto. As this is a sizeable increase in voting share. But if it remains at 50%, or thereabouts, or increases share only with a decrease in turnout (compared to the indy vote, or the last General Election), then the mandate simply isn't there, as it is a similar result to the previous elections, and therefore shows no major swing towards a want for independence post ref.
