I think presidential elections are ripe for investigative stories. This one, recently, caught my eye: https://www.nbcnews.com/politics/2020-election/bloomberg-says-he-nearly-eliminated-stop-frisk-mayor-he-fought-n1144266
Data is used to rebut Bloomberg's claims that he tried to end stop and frisk. The numbers under this transition: "After taking office in 2002, Bloomberg greatly expanded the program" are used to show to what extent Bloomberg expanded the program. I believe the numbers are used to hold Bloomberg accountable and to add context/details.
I think it could have been improved by some kind of visualization of the expansion under Bloomberg--a bar graph or some kind of chart could have brought home the point.
