I can see why you would think that, but it’s actually not true. As I explain in the article, he commuted more sentences than the last 9 presidents. But look at the second graph — that’s the total number of clemencies for the last nine presidents, including full pardons. Obama’s only killing it at one very specific type of clemency grant. The White House is excluding the other types of grants (namely, actual pardons) in its statistics, which is confusing to people.
