I went back and looked at the collection of speeches by the three contenders in the 2008 U.S.presidential election, not from the point of view of spin, but just looking at what they were about. The results were a little surprising. Despite all of the thinking and polling that goes into a campaign, the speeches were about only three topics.
These three topics are: the economy, associated with words such as crisis, jobs, plan, pay; security, associated with words such as war, threat, Iraq, allies; and family, associated with words such as parents, children, living. This last group features only early in the campaign and a single speech by Obama given on Fathers Day.
It’s no surprise that these topics appear. What does seem surprising is how little else was mentioned: other topics words are all hidden in the center of the figure indicating that their pattern of appearance in not very interesting.
