2012 - Write a new one or dust off the old one?

Write a totally new one and it stands clean and new for a new election. Or dust off the old blog from the last election and use it as an interesting link to the past?
Well I thought the reflective option of dusting off the old one and giving a link to the past 5 years as well as discussing the issues I intend to focus on for this campaign would be the best, most complete option.
Hope you agree.
