Pollster.com presents a series of  tag clouds from last night's Democratic Presidential debate in South Carolina. Comparing the tag clouds for the different candidates gives you (some kind of) a measure of the way each of the candidates uses words. I posted the following as my observations:

Obama's tag cloud is almost devoid of words with powerful emotional content. Contrast that with Hillary. Edwards isn't bad, either. This is a weakness for Obama. If his words were not powerful, how will people remember him, unless his personal presentation made up for the weak content.

One of the key aspects of right-wing framing is the use of emotionally loaded language, in particular words that code for powerful images.
