I’m increasingly fascinated by the use and manipulation of language in politics, and came across this site recently. Chirag Mehta has just created this site where he’s analysed all the major speeches by US Presidents since 1776, and created a tag cloud of the most frequently used words.
Really interesting. ‘Terrorism’ comes up most under Dubya, Clinton liked ‘Families’ and economic stuff, ‘Freedom’ was very popular under Reagan, Nixon liked ‘Committment’.
