Writing public affairs commentary is rather like running one of those fantasy sports franchises where you "draft" NFL players and then score points versus the other obsessives in your league based on how well your boys do on Sunday, while the women in your life (if any) roll their eyes. In other words, punditry is basically just something that guys do, like pretending they own a football team. It's pretending you run the world.
Granted, this is pretty pathetic. On the other hand, the people who actually do run the world are far less competent at their jobs than the people who run NFL teams, so there is some justification for commentary. On the other other hand, is there any evidence that the people who run the world learn from good commentary?
On the other other other hand, unlike in a fantasy football league, nobody keeps score in punditry to see if you are as smart as you say you are.
