Hillary Clinton left her audience cold in Iowa City on Thursday night, after she spoke for less than five minutes to a crowd of more than a thousand people, some of whom had lined up for more than an hour to see her.

After a day marred by a new poll showing Bernie Sanders leading her by eight points in Iowa, Clinton might have been expected to go for broke during a rally at the University of Iowa, which featured a performance by popstar Demi Lovato.

But Clinton did not refer to the Vermont senator, or much else, in her speech. The lack of length and substance of her address appeared to upset some in the crowd.
