As much as our friends in parliament sometimes make it out to be, it is not purely a match. There is no "underdog" in Brexit; there is one team, the UK, with two options: remain or leave. Choosing a bad option affects everyone equally (except a few career politicians).
With all the shouting and finger pointing it's easy to lose track of this fact: it is not a competition. We're in this together. We're a family, and we might be cutting off the nose to spite the face.
But it has morphed into an us-vs-them issue (brexiteers vs remainers, not even immigrants), and through the lens of competition we only see the finish line.
