Word clouds for every Presidential inauguration speech
from the NYTimes.
What first jumped out at me was the clear difference in rhetoric between the Red and the Blue - at least in recent times. The Dems use words like "responsibility" and "spirit" and "people" while the Repubs stick to fascist standards like "freedom", "nation", and "citizen".
Further investigation lead to this: before WWI there is almost no mention of the word "world" - at least not often, but afterward it is prominent in almost every speech. I guess we can call that progress, in some respects?
