As expected, the main message of the day looks to be "stable and secure health care" as displayed inside the Comcast Center. This photograph was taken in the middle of a stadium 'wave' early in the day.
An iPhone was used to photoblog live before and during the event. More photographs, taken with a Canon 40D, were added afterward with time stamps set to match when those were taken. In some cases, a live blog entry's photograph was replaced with a higher quality photograph taken at the same time.
