Shout. Have fury permanently on your face and anger in your eyes. Shout to hide the vacuousness. Talk about the puppet show of Conservatives and Liberals as if they are not masks on the same force. Tell the people the puppet show is real. That will 'Save the Kingdom' - a 'Kingdom' created by the very people you claim to oppose. A 'Kingdom' that enslaves its people by getting them to hand their power to people like you. 
Yep, that'll do it. Ain't it great to have a saviour?
