Bernie Sanders of Vermont and former South Bend, Ind., Mayor Pete Buttigieg declared victory in the election that took place three days earlier.
Despite 97 precincts reporting results from the caucus, the news agency reported that it will not call a victor, as Buttigieg currently leads Sanders by three state delegate equivalents out of 2,098 counted -- or a margin of 0.14 percentage points. At the same time, Sanders, at this point, leads Buttigieg in the raw vote count.
“The Associated Press calls a race when there is a clear indication of a winner. Because of a tight margin between former Mayor Pete Buttigieg and Sen. Bernie Sanders and the irregularities in this year’s caucus process, it is not possible to determine a winner at this point," said Sally Buzbee, The AP's senior vice president and executive editor.
The hesitancy to declare a winner comes shortly after Democratic National Committee (DNC) Chairman Tom Perez asked the Iowa Democratic Party to conduct a recanvass. That is not a recount, but rather a check of the vote count to ensure the results were added correctly.
