Short answer for me is that it's confirmation bias. We all do it. It's the reason more left-wing people read the guardian or Mirror. We usually want to read things that affirm our opinions more than challenge them.

As Jon says, the Express is also pretty much the most ridiculous mainstream paper in the UK. It really doesn't have the investigative journalism or spectrum of opinion that the Mail does, let alone anything else.

That said, people haven't necessarily been 'taken in'.

On paper 1, assume thats from around 2010? - I think many would have agreed that it was time for something different.
Paper 2, assume thats from 2017? - We don't know what Corbyn would have done, but given we are talking about market disruption today, I think it's fair to say it would have reacted worse to Corbyn than May
On paper 3 - About keeping Boris in the job? Well, you are all now criticising the tax cuts and market reaction now he's gone..maybe they were right!?
On paper 4 - Maybe they are right. It's too soon to tell.

Murdoch (if hes still around) will never back the losing horse. Very significant to see how the Sun etc reports on things. They will be coming round to Labour and Labour know how important that is.

I dont mind Starmer at all. I agree he's a bit dull, a bit technocratic. Of recent PMs he reminds me most of Blair or Cameron. He does increasingly look a safe pair of hands though.

My more general point is that every party in power of left or right has been criticised, voted out, hated, admired, slated, adored in the last 12 years..and the same will happen in the next 12. It matters a lot less than many of us think who is in power.
