The event was co-sponsored by the University Democrats and the Young Democratic Socialists, and it was held in the Main Lounge of the Iowa Memorial Union. The main lounge’s capacity setup is 1,200 if it’s a theater setup. But so many people showed up, they needed an overflow room for everyone. Some estimated that overflow crowd numbered at least an additional 500, maybe more. Read on to see crowd photos and learn more about tonight’s rally.
