David Simon: Paying 13 percent in income taxes isn't anything to brag about

Simon called Romney's refusal to release more of his tax records absurd.

"I can’t get over the absurdity of this moment, honestly: Hey, I never paid less than thirteen percent. I swear. And no, you can’t examine my tax returns in any more detail," Simon wrote, in Romney's voice. "But I promise you all, my fellow American citizens, I never once slipped to single digits. I’m just not that kind of guy."

"This republic is just about over, isn’t it?" Simon concluded.
