He is an idealist, and that makes him dangerous, naïve and utterly unsuitable for a role like leader of the opposition, let alone Prime Minister.
He has also been proven to be every bit as hypocritical as any other politician yet maintains the same air and tries to project the same image.
On that basis he is dangerous, and so regardless of the respect I may have for some of his ideals, I hate the prospect of him becoming prime minister. It would be disastrous.
