Political Frequencies
I eliminated the smaller, high frequency words such as "a", "the", "this", etc. I left the pronouns—they strike me as critical in the rhetoric of unifying the "us" against the ominous "they."
The list seems easily to capture the major themes and line drawing of the speech.

Not sure when I'll have time to get to it (the "to read" pile is tall enough to kill me in an earthquake), but I'm really looking forward to reading Paul Chilton's Analysing Political Discourse: Theory and Practice (Routledge, 2004).
UPDATE Looks like I wasn't the only one who had the idea. See here and here.
