Pro-independence parties have taken around half the popular vote in the most recent Holyrood and Westminster elections (more than half in the 2015 Westminster election) which suggests that the movement spawned by the independence referendum have united behind that cause and that support has not diminished (if anything it's increased slightly), while support for the Union remains largely split between Labour and the Conservatives, therefore uneffectively mobilised in a first-past-the post general election context. I don't know where you generally get your news, but most print and broadcast media in the UK is generally hostile to Scottish independence and likely to seize upon any headline that can be spun as a "Blow for Sturgeon".
I don't know if anyone can really trust opinion polls anymore, but in the most recent aggregate of polls, John Curtice suggests that the apparent lack of appetite for a second referendum may be tactical among supporters of independence:
"Given the Yes side still seem to be behind in the polls (albeit no more than narrowly) some supporters of independence may want Ms Sturgeon to stay her hand for fear that a second ballot would be lost. In short their opposition may simply be tactical. If that is the case, they might not prove so supportive of the Prime Minister should she try to stop any attempt by Ms Sturgeon to hold a second ballot.
Distinguishing between these two explanations is nigh on impossible given the polling evidence currently available. But one clue that perhaps the reluctance of some Yes voters is more tactical than principled comes from two further questions on the subject posed by Panelbase, in one instance for the Sunday Times and one for Wings Over Scotland. In each case the poll contained two options for an ‘early’ referendum – one holding a ballot within the two year time frame for the Brexit negotiations and one doing so after those negotiations are over and the UK is set to leave the EU. Both these polls suggest that most supporters of independence are just as keen on one or other of these early referendum options as unionists are reluctant to see them pursued."
What do you want the Labour Party to be? Like, what would your ideal Labour Party be? Do you want them to revert to full-blown Blairism (cause that went really well)? Not having a go, just curious.
