I think that I misunderstood what Henry meant when he took the time to describe himself as a Tory on his intro VT. He also talked about admiring Johnson. But I think the second bit is actually the bit that matters more to him, and I think it was revealed a few days ago that he's not a party member. I had assumed that he was a bit more politically engaged.
What today's episode revealed was that he saw politics, or at least the job of PM, as being something that required charisma rather than competence... and that somehow a deadly fuckup followed by something that wasn't a fuckup was cause for praise.
