I feel like there's something of a Mark Twain moment going on - I especially like the Telegraph suggestion that the SNP have "lost their hold on Scotland" - and hence invested a few minutes looking at historic election results.
During the mid 20th century, Scotland was split along traditional lines between the Labour and Tory parties, with the latter often securing in excess of 40% of the votes cast.
Dramatic changes occurred from 1970s onwards with the SNP polling 21.9% (1974), 30.4% (1974 again), 17.3% (1979), 11.8% (1983), 14.1% (1987), 21.5% (1992), 22.1% (1997), 20.1% (2001), 17.7% (2005), 19.9% (2010), and 50% (2015).
Putting this in context, the Tory votes for the 2005-2015 period were 15.8%, 16.7%, and 14.9%. Labour during the same period were 39.5%, 42%, and 24.3%.
What therefore happened, during that period, was that the Labour vote collapsed - dramatically - and the SNP reaped the benefit.
Now it looks like the current results are:
SNP 36.9% (-13.15)
Tory 28.6% (+13.7%)
Labour 27.1% (+2.8%)
Now at the same time, we have the 2016 Holyrood elections whereby (taking the first preference share):
SNP 46.5% (+1.1%)
Tory 22.0% (+8.1%)
Labour 22.6% (-9.2%)
I observe in the passing that this brough the SNP their historic third consectuive term at Holyrood, although some media sources and politicians would have had you believe that the ball was on the slates.
More recently, the local government elections (first preference):
SNP 32.3% (-)
Tory 25.3% (+12%)
Labour 20.2% (-11.4%)
So what conclusions can we draw from this?
First and foremost, it's clear that the 56 out of 59 Westiminster seats in 2015 was massively over historic polling levels and more recent trends. Excluding that result, the SNP remain above their historic levels. Put another way, and slightly tongue in cheek, just because 2009 Right Bank Bordeaux was a spectaculary good vintage does not therefore make the successor vintages rubbish by default.
Likewise the 2015 result was not necessarily reflected in the much more closely fought Holyrood and local council elections in the subsequent years. Notwithstanding that 3 horse race at Holyrood level, the SNP continue to secure the largest number of votes and govern there.
What we therefore have is a shift away from the SNP of a substantial, but not total, part of the electorate that moved towards them in 2015 back towards the two Unionist parties - notably the Tories, who have the least uninspiring and most media-friendly persona of the Scottish opposition parties at present.
Whether this shift is based upon those unhappy with SNP governance at Holyrood, those who oppose independence, or even pro-Brexit voters will doubtless be pored over in the press over the next 24 hours. Perhaps some support the social democrat policies at home nation level - free prescriptions, no student fees, and so on - inasmuch as none of the other parties hitherto seemed willing to deliver such things, but don't see them as players on a UK stage to the same extent? Perhaps it's just "soft" Unionists tactically voting?
What is clear, however, is that in the case of the media we're seeing a lot of hyperbole suggesting the end is nigh rather than a return to business as normal. The Conservatives have clawed their way back to 1995 voting levels, but no more, whilst Labour languish in what was once one of their heartlands. The one thing that the pundits probably have correct is that it knocks IndyRef2 into the long grass for an extra year or two, but we shall see.
