YouGov with fieldwork on the 3rd and 4th March, as the First Minister and the former First Minister were grilled at length on the TV, has reported a shocking collapse in SNP support, from 51% to 50% based on a cute but insignificant sample of 147 over-18 year-olds.
I blame her bare-faced integrity.
Support for the Scottish Conservatives also fell by 1% but but support for Labour plummeted by 4% in the wake of the appointment of new leader, Anas Sarwar.
Sarwar must be relieved as his boss also lost support to give Boris a 13 point lead, up from only 5 points on the 26th February. The vaccine rollout boost effect?
Also interesting, but only in Scotland, was a surge in the dinna kens from 9% to 16%, most of them in the Labour and Green groups.
