Promise vs. Fight

HuffPo has an article today comparing words used at the DNC and RNC conventions. They've got a pretty good visual, but I thought I'd wordle some of the speeches to see what words the individuals used most. In wordles the words are sized based on how often they are used in the selected text. Looking through the galleries on wordle, I realize I'm not the first person to do this, but whatever...

Let's start with the wives. Here is Michelle Obama's speech. The words that stand out are 'Barack', 'work', 'world' and 'people'.In Cindy McCain's speech you see 'John', but 'Country' instead of world. Interesting...
The VP Candidates starting with Biden... 'Barack Obama Change' clearly stand out here. And he mentioned John McCain more often using his first name than his last. Sarah Palin used McCain's surname more often (she is his junior after all and has not claimed - like Joe Biden to be his 'friend'). She also used the word 'Man' quite a bit. I feel like if this was Hilary Clinton or anyother female politician making a VP acceptance speech that would not have been the case.

Then we come to John McCain's speech inwhich his most used word was 'fight' (is anyone surprised by this?)....

In comparison Obama's most used word was 'promise'. And I believe he does.
