As a British citizen, we've certainly ejected cunts from power.

The big difference between our system and the US system is that the US system is codified in a single document and as a result it doesn't evolve except through rare amendments. The British constitution is written through precedent. If a situation hasn't occurred before then we decide what to do today. We don't try to take the 250yo (or more) words of people who had never imagined the situations of today and try to apply the right to bear arms on AI powered kamikaze drones.
