It seems that, as I predicted, the election has polarised into a straight Labour-Tory fight with some modest intervention from the Liberals. The trajectory of the polls is actually pretty similar to 2017, bar the Lib Dems being stickier than last time round - it wasn’t until the final week of the campaign when the really scary polls (for a Tory) putting Labour and the Tories neck and neck started to come out, so I wouldn’t rule it out this time either, given that there’s still nine days for Johnson to screw up big time.
Looks to me like the final week was just a continuation of the previous trend, i.e. no tremendous Labour surge within the final couple of days. Moreover, as others have pointed out, the Tory lead at this point is slightly larger than what they had going into the final week two years ago.
