© Des Moines Register Iowa Poll - February 2020.

The Des Moines Register, CNN and Selzer & Co. have made the decision to not release the final installment of the CNN/Des Moines Register/Mediacom poll as planned this evening.

Nothing is more important to the Register and its polling partners than the integrity of the Iowa Poll. 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.

While this appears to be isolated to one surveyor, we cannot confirm that with certainty. Therefore, the partners made the difficult decision to not to move forward with releasing the Iowa Poll.

The Register has published the Iowa Poll for 76 years, and it is considered the gold standard in political polling. Selzer & Co., which conducts the poll, is recognized for its excellence in polling. It is imperative whenever an Iowa Poll is released that there is confidence that the data accurately reflects Iowans’ opinions.
