This is interesting, not seen this kind of analysis until now.
According to this poll, the average Labour polling lead is 24 pts (slightly less than YouGov have quoted but roughly the same as other pollsters). Importantly though, if you look at the seats Labour would target, the 150 closest contested seats, the poll lead is even wider.
It seems that this 20-25% of the vote the Tories are clinging onto is disproportionately concentrated in their safest seats. It already looked bleak for them but this just makes it way worse.
The funny thing is that their obsessive 'Stop the Boats'/Rwanda bollox is turning off moderate Tories and swing voters who are concerned about other issues.
At the same time they losing the the very people they are targeting with this nonsense to Reform because even the racists and xenophobes can see that the Rwanda policy is not going to work.
