People will say this is comms, but really it’s a function of policy (there has been a flurry of action) and character/content (Burnham is just better at this stuff than his recent predecessors, including BoJo).
Burnham seems to be commanding the battle for the attention economy 36% have seen content from Burnham - including over half of 18-24 year olds. 16% have seen Farage content, no one else cracks 10%. Some of this will be the prime ministerial pulpit; but it’s lodging with people.
