David Foster Wallace/YMMV

"08/15/1730h....Fifteen whole minutes both in- and outside the huge STATE COMPTROLLER ROLAND BURRIS tent fails to uncover the tent's function."
 * Harsher in Hindsight: The short story "Good Old Neon" from the collection Oblivion details the life of an extremely intelligent and self-aware man who after a long struggle with depression commits suicide, including several paragraphs detailing his final decision to do so, his thoughts as he prepares, etc. Disturbing to begin with, really uncomfortable since Wallace's suicide after years of depression and failed treatments.
 * "The Depressed Person" from the earlier collection Brief Interviews With Hideous Men has a similar effect. Although the character is a woman and an ordinary office worker, you can, in hindsight, see very plainly that Wallace writes from his own personal experience. Since he was writing even earlier in his career, the story's ending--with the title character opening up to one person and then just leaving it there hanging--is all the more heartbreaking, as you start to think What Could Have Been (and worse, what might have not been).
 * Hilarious in Hindsight: There's a fair number of these in some of his nonfiction, but one that stands out to the political set is in this quote from "Getting Away From Pretty Much Already Being Away From It All" (collected in A Supposedly Fun Thing I'll Never Do Again):

"08/15/0620h....All they had was a little kid's tablet with that weird soft gray paper and some kind of purple brontosaurus-type character named Barney on the cover."
 * And more generally, while describing the writing material available at the State Fair Gift Shop:


 * "Up, Simba" follows the primary campaign of a politician who was staggering in his refreshing honesty, ability to get young people involved in politics, and promises of change. Meaning, of course, John McCain.
 * True Art Is Incomprehensible: He's quite clear in his nonfiction, but in his fiction, less so.
