Release of key Iowa poll canceled less than 48 hours before caucuses

An Iowa poll, long considered the most credible in the state and closely watched by political campaigns, will not be released Saturday night as planned. The poll from the Des Moines Register, CNN and Selzer & Co was set to be one of the final Iowa polls ahead of the state's caucus on Monday.

"Today, a respondent raised an issue with the way the survey was administered, which could have compromised the results of the poll. It appears a candidate's name was omitted in at least one interview in which the respondent was asked to name their preferred candidate," Des Moines Register executive editor Carol Hunter said in a statement.

Hunter said the incident appears to be isolated to just one surveyor but could not confirm with certainty and "therefore the partners made the difficult decision to not to move forward with releasing the Iowa poll."

The New York Times first reported the poll was being pulled minutes before the results were scheduled to be announced. The Times reported it was Buttigieg's name that was left off.

Lis Smith, a senior adviser to Pete Buttigieg's campaign, confirmed Saturday night on Twitter that the campaign had received a report from a recipient of the poll that not every candidate was named. The campaign shared this information with the organizers of the poll, who she said "conducted an internal investigation and determined not to release it."

"We applaud CNN and the Des Moines Register for their integrity," Smith said.
