Velda City is nearly all black. I'd be surprised if those votes didn't come in above 95% Obama. I just heard on another news station that the wait was as much as 7 hours, and that some people were effectively disenfranchised because they couldn't wait that long.
There were very long lines (about an hour wait) in the morning rush, but things ran very smoothly otherwise. I was planning to entertain people here waiting in line (wish I'd known about Velda City!) for the late rush, but it never happened. At my polling place, they had it set up so that maybe 100 people could work on filling out their paper ballots at the same time. Even when the lines were long, they were moving.
From what I heard from the local Obama HQ, things were about the same all over the City.
