Presidential rhetoric

I've seen earlier examples of this approach, but Chirag Mehta has put together the best example of tag clouds of US Presidential Speeches online.

For the uninitiated, tag clouds are word lists, weighted by some aspect of their use (e.g., most common, most recent).

Drag the slider bar to get a sense of what Presidents from Washington (1) to Bush (43) talked about in over 360 speeches, letters, and official documents.
