Des Moines County Democratic Co-chair Tom Courtney tells CNN that he tried for 15-30 minutes to send in results on the mobile app before giving up and calling in to the hotline.
When that didn’t work either, he made plans to call in the results tomorrow morning.
"I will try tomorrow, but I have a doctor's appointment in the morning so it might be 10 a.m. by the time I turn in results," Courtney said.
He had 118 caucus goers, down from more than 200 from past election cycles. His caucus ended around 8:30 p.m. local time.
