Iowa's nightmare revisited: Was the correct winner in the Democratic race called?

Sanders campaign aides told the Register they’ve found some discrepancies between tallies at the precinct level and numbers that were reported to the state party. The Iowa Democratic Party determines its winner based not on a head count, like in the Republican caucuses, but on state delegate equivalents, tied to a math formula. And there was enough confusion, and untrained volunteers on Monday night, that errors may have been made.

“We feel like that there’s a very, very good chance that there is,” said Rania Batrice, a Sanders spokeswoman. “It’s not that we think anybody did anything intentionally, but human error happens.”

Team Sanders had its own app that allowed supporters and volunteers to send precinct-level results directly to the campaign. At the same time, caucus chairs sent their official results to the state party, either over a specially built Microsoft app or via phone. Sanders aides asked to sit down with the state party to review the paperwork from the precinct chairs, Batrice said.
