I think this photo has such amazing atmosphere. It makes voting seem like a sacred act, which I suppose in some sense it is. The caption reads:

Haitians vote late into the night by candle light at a polling station on February 7, 2006 in Port-au-Prince, Haiti. Many voting stations were overwhelmed by the amount of people showing up to vote and stations had to be kept open all night to make sure everyone could vote. For the most part, the first election since Aristide went off with little violence. (Michael Orin Kleinfeld)

Here is the rest of the photoset. [UPDATE: I'm not sure what happened. That whole photoset vanished. here's the photostream it came from; maybe the photographer found a buyer.] FURTHER UPDATE: Now the photo is back up. HERE is a link to a big version, and HERE is a link to the photoset.
