The Sunlight Foundation has released a wonderful program (Capitol Words) that allows one to chart the number of times that members of the House and Senate have used specific words on the floor. You can chart the number of occurrences by party (try “debt” and see that both parties are concerned about the debt, albeit only when the president is from the other party). You can also compare different words (try “Koch” and “Benghazi” for example). I only wish that one could save the charts. H/t Shane Goldmacher.
