The Iowa Democrat Party has released a report that largely puts the blame on the national party for the delayed results in the 2020 presidential caucus. 

The report concluded the Democratic National Committee was instrumental in the delayed development of the phone app that was used to collect data from caucus sites and that failed to convert data on caucus day. 

"Without the DNC’s intervention in that process, the IDP may have reported results in real-time as it intended," according to the report, initially reported on by the Des Moines Register.

The report also concludes that officials in Iowa understood less than a week before the February caucus that less than a quarter of local precinct chairpersons had successfully downloaded and accessed the Shadow Inc. app.

The report also found blame with the state party, concluding fit failed to create a dependable back-up system for tabulating the caucus results. 

"The IDP should have taken aggressive steps to scale up its telephone back-up reporting system at that time," the report states.

"In the interest of clarity and public reassurance, the IDP commissioned this self-critical report to help guide conversations as we move forward," said Mark Smith, state Democratic Party chairman. 

Iowa's caucus traditionally begins the presidential nominating contest, though that role (and the role of caucuses in general) was called into question this year. Weeks after the caucus, the state certified former South Bend Mayor Pete Buttigieg as the winner. However, faulty reporting and potential errors in vote counting meant that some outlets – including the Associated Press – refused to declare a caucus winner.
