No, it's not because I regularly read the Minneapolis Star Tribune, where Sack has been using his art to put a spin on events since 1981.
It's not even because, as the Pulitizer jury put in selecting Sack, he produces a "diverse collection of cartoons, using an original style and clever ideas to drive home his unmistakable point of view."
It's because of his cartoon today, which fittingly on April 15 skewers the U.S. tax code. Clip the snippet at left to see Sack's full drawing.
Also nicely timed for Tax Day, Sack's Pulitzer Prize brings not only admiration (and probably some envy; I used to work at a newspaper, so I know these things!), but also 10,000 taxable dollars.
