What kind of 'third front' do you want? The fact that you don't actually detail what sort of politics it would have makes me suspicious. Who is it that you want me to give power to?
You know what I don't really get? Why do we need anyone to give power to? Keep it to yourself. We've got everything we really need to make ourselves happy and live our lives. Why do people so desperately need someone to reign over them? This sounds like a Stockholm syndrome.
