I downloaded the transcripts of all of Obama and McCain’s speeches from their respective official websites from March 25th, 2008 to the present and then put them each into Wordle.

Wordle gives greater prominence to words that appear more frequently in the source text.

I used 51 speeches by McCain and 61 by Obama.

McCain’s site only had transcripts from March 25th to the present and I figured that was plenty of data for my purposes.
