Up to 1,500 demonstrators gathered in Daley Plaza for yesterday’s Tea Party rally—a protest against taxes, President Barack Obama’s policies, abortion, and many other things offensive to (ultra-)conservative sensibilities. The “tea baggers,” as they’re commonly called, aren’t united by any clear political belief or objective, which makes it difficult to describe them. But they’re all angry about something, and for now that’s enough.

Composition-wise, the rally looked like many other Tea Party protests I’ve seen photos of, with guys dressed up as patriots, tea bags used as fashion accessories, and flags galore. But while the signs blared angry slogans, the carriers themselves appeared calm: One polite man in the crowd even refrained from standing in front of me for about 15 seconds while I took a few shots. Good midwestern manners still trump vitriol, perhaps.
