Activists and campaigns for Democratic presidential candidates are frustrated and on the edges of their seats as results in the Iowa caucuses are unexpectedly delayed.

The Iowa Democratic Party initially said that the first precinct results could come in as early as 8:30 p.m. CST — an hour and a half after the caucuses started. As of 9:30 p.m. CST, there were no results reported. The party said two hours after the caucuses started that they were conducting “quality control” and that the delay was “out of an abundance of caution.”
