Well, for one, they are 'populist' which is a word only causing horror to those who are opposed to true democracy.
Secondly, they are NOT LibLabCon or Green or BNP.
They are in fact, rather ordinary but that in itself is what makes them exciting!
Nonetheless, I can see a distant time when they will take power but will they remain as untainted as we voters would wish, the closer they get to that ideal?
Only with a rapid rise to power are they likely to keep the essence of what currently makes them tick.
