I think you could follow Paul's thinking and interests fairly easily if you followed his blog. He has deleted some posts on there now though. His previous and current positions both include a hostility to identity politics and liberals, for one. And in particular I think he was especially concerned about how these two failed to tackle Islamic extremism adequately.
I think if you add a pro-working class take on Brexit to the mix (with further disdain for the liberal left) and, I assume, the annoyances of trying to work in academia for a while, then I don't think it's that hard to understand.
I might be wrong, and I've only met the guy a couple of times in the noughties personally. As with Paul Embery there is a more cynical take which is that the money and clicks led them both in a particular direction, but Paul (ex-CW) was quite a talented guy imo and could have turned his hand to a bunch of different things.
