DES MOINES, Iowa (AP) — A new mobile app was supposed to help Democratic officials quickly gather information from some 1,700 caucus sites throughout Iowa. Instead, it's being blamed for delays that left the results unknown the morning after the first-in-the nation nominating contest. Glitches with a new mobile app Monday caused confusion, and some caucus organizers were forced to call in results for the state party to record manually, introducing delays and the possibility of human error.
