I believe the technical term for it is "mad as hats". Still washes out to a Tory lead all the same. Just size of it. And where. Labour are running the marathon pulling an anvil behind but that's an old story.
Agreed on the mad part, and that polling is all over the place. The Guardian poll struck me as scary not so much for the reported lead, but that a government so venal and chaotic is still not being dented by the Opposition.
Indeed, the continued evidence that former Labour voters are increasingly prepared to vote Conservative Brexit areas seems to undermine the 'fence-sitting' approach, and that any election in the pre-Brexit timescale is lilley to be a single issue election shorn of previous loyalties.
As in Thatcher's heyday, once previously tribal Labour voters decide they can vote Tory, they are not easy to get back.
As I've written before, I think the only viable strategy for Labour is to become a fiercely Remain party, almost certainly on a Revoke Article 50 platform. With a very different leader to sell it.
I think the only lesson the polls are giving us is that a very clear position on one or other side of the Brexit issue is necessary. Or maybe that the British (English?) electorate really wants a dictatorship rather than standardised bananas.
