And you're surprised? In my view, the various different Tory leadership elections since about 1989, they've all had some sort of "Game Of Thrones"-esque quality about them. Other leadership elections for other parties, also tend to have a similar quality about them, although mostly a bit less so. Admittedly the coverage of these various contests, may have helped create that impression somewhat, but that's how I've seen it over the years. Also admittedly, this particular contest does seem more "Game Of Thrones"-esque than previous ones.
I’m not sure I follow.
There's always a lot of metaphorical backstabbing in these contests, and none of the people in these contests come across as particularly pleasant, much like many of the characters in Game Of Thrones.
Because they aren't particularly nice people in reality
