When thinking of powerful politicians expressing their authority we might be inclined to imagine them sitting on a throne of at least a big chair making decrees. Perhaps they're standing up and pointing the way to the promised land while delivering big oratory. But this is wrong. When thinking about modern politicians working we should probably think about them using the telephone. They could be calling to negotiate a hostage release or dialling in to discuss a trade deal. Mostly however it is mundane. But they do it a lot. Modern political power exists at the end of a telephone. Even if you're only texting.
