Iowa Democratic Party Communications Director Mandy McClure said the party found "inconsistencies in the reporting of three sets of results."
Here's the full statement:
We found inconsistencies in the reporting of three sets of results. In addition to the tech systems being used to tabulate results, we are also using photos of results and a paper trail to validate that all results match and ensure that we have confidence and accuracy in the numbers we report. This is simply a reporting issue. The app did not go down and this is not a hack or an intrusion. The underlying data and paper trail is sound and will simply take time to further report the results.
About the three numbers: Iowa Democrats are releasing more information about caucus results than usual this year. There are three sets of numbers we're expecting:
- State delegates won: Each precinct sends delegates to county conventions, who then send delegates to the state convention. The "state delegate equivalents" — the number that'll be the focus tonight — are the estimated number of delegates candidates have won to the state convention based on their results in each precinct.
- The first alignment: The state Democratic Party will release the total number of people at each precinct that lined up with each candidate at the start of the caucuses.
- The second alignment: Then, after realignment — the process where those who fall short of 15% are eliminated, with their supporters either choosing a different candidate to back or going home — the state party will release those raw vote totals as well.
