I have found an article from early on in this election - YouGov on the "demographics dividing Britain". Makes sense, the anti Corbyn bias mentioned in previous post might work for an older TV audience so Andrew Neil and the others are not getting much feedback.
Not sure how this is working out over time. It may get more polarised. My impression is that on Twitter the Conservatives are tending to use display ad styles. There may be some reaction to this.
Blog is still mostly looking at newspapers but I will spend more time with social media for context. TV and radio is turning up as clips.
