'Inconsistencies' Delay Results Of Iowa Democratic Caucuses

The Iowa Democratic caucuses faced delays in reporting results due to inconsistencies. The Iowa Democratic Party used photos and a paper trail to ensure accuracy, denying any hack or intrusion. For the first time, three sets of results were released to increase transparency, causing delays. The caucus process involves groups declaring their preferred nominee, with non-viable candidates' supporters having options to switch or remain uncommitted. The second vote determines winners, and the final tally calculates delegates for the state convention.
