"Of the 54 submissions from the Buttigieg campaign, 37 precinct submissions contained the information required to request a recount," a state party spokesman said in a statement to POLITICO, when asked why some precincts were rejected. "Of those precincts, 14 were determined to be eligible for a recount. The remainder of the precincts were determined ineligible for recount" because they would not change the delegate results, the spokesman added.

The state party said it "transmitted to the campaigns further details on costs associated with the recount and the timeline going forward," and that the two campaigns have 24 hours to respond "with financial information to proceed with the request."

The recount is expected to start Tuesday and last for two days.

Prior to the recount, results from the state party following a recanvass showed Buttigieg with a very slim lead over Sanders in state delegate equivalents, 563.2 to 563.1, or a difference of about four hundredths of a percentage point. The Associated Press has not declared a winner in the first-in-the-nation caucuses, which were held on Feb. 3.

In the post-recanvass results, Buttigieg was projected to win 14 delegates to the Democratic National Convention, while Sanders was projected to get 12. However, a swap in the lead in state delegate equivalents — which the Sanders' campaign asserted will happen after a recount — could ultimately change how many national delegates each candidate gets to the national convention.

Iowa's caucuses, which took place over two weeks ago, have been marred by chaos. Results' release were initially delayed, and party-reported results also contained apparent errors. The problems ultimately led to then-state party chair Troy Price to resign.

They also increased the attention on the next caucuses on the calendar: Saturday in Nevada. Party officials, both locally and nationally, have scrambled to avert the same issues, including canceling plans to use a similar app to help tabulate results, publicly releasing training materials and downplaying the timeframe for when results can be released.

“Our number one priority is getting this right and making sure the results that are released are accurate,” Nevada Democratic Party spokeswoman Molly Forgey told The Nevada Independent on Friday. “But it’s our plan to have results released on Caucus Day.”
