Some perspective is in order. The Tories still enjoy a lead outside the margin of error, in every single poll taken so far. Let's look at the last five polls, released between 27 May and 1 June. The Conservative lead varies from +12 (ICM, 29 May) to +3 (YouGov, 31 May). Taking the mean of these five, we have Con 43.4, Lab 35.6, LibDem 8.2, UKIP 4, for a Tory lead of +8. Plugging this into the UK Polling Report swingometer results in a Conservative majority of 46.

Twenty-five months ago, David Cameron would have given his left testicle for these polling numbers. The boost in Labour support won't necessarily hold up; and it appears to be driven by younger voters, who may or may not turn out on election day.
That said, this election was widely expected to be a walkover for the Tories, with excitable talk of a landslide of 150 seats or more. Expectations were driven so high that Theresa May could win a majority of 40 or 50 seats, the best Conservative result in 30 years, and it would still feel like something of a defeat.
How has this happened?
