I added the transcript for the Ohio Democratic debate held on February 26, 2008 to the interactive Transcript Analyzer. The image below is smaller (and more blurry) than from the application but gives a rough idea of what was discussed by which candidate and when. Here are the primary topics covered in order:
It's also interesting that 'immigration' was mentioned in passing only once during this debate but was a primary topic in Texas. Also 'education' was not given any real attention.
Democrat Debate - Feb 26th, 2008
I have made another minor refinement to the application. Beside the word lines are shown the number of times each word was used by each candidate. For example for this debate 'Iraq' was used 8 times by Obama and 5 times by Clinton.
