Des Moines Register

UPDATE: 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.

The Des Moines Register, CNN and Mediacom will release an Iowa Poll on the Democratic presidential candidates on Feb. 1, two days before the Iowa caucuses.

The poll will ask likely Democratic caucusgoers their top choice for president among the candidates for their party’s nomination. Results will be published on DesMoinesRegister.com and CNN.com and will appear in the Des Moines Sunday Register.

The much-watched poll, called the “gold standard” in political polling, will be released in conjunction with a CNN Special Event: “Iowa Caucuses: The Final Poll,” televised from Des Moines’ Drake University.

CNN’s show will begin at 8 p.m. CST.

CNN’s Chris Cuomo will lead the show and will be joined by CNN colleagues John King, Dana Bash and David Chalian. Brianne Pfannenstiel, chief politics reporter for the Register, and J. Ann Selzer, president of the Iowa-based polling firm Selzer & Co., which conducts the Iowa Poll, will also participate.

Ticket information for those who want to attend the show will be released at a later date.

The Iowa Poll, a Register exclusive since 1943, will also ask likely Democratic caucusgoers other questions about the upcoming Feb. 3 caucuses.

The Register and CNN have joint control over deciding poll questions, when results are released and related content. Their partnership is also in collaboration with Mediacom, the largest cable company in Iowa and the nation’s fifth-largest cable company based on video customers.

In past Iowa Polls during the 2020 caucus cycle, former Vice President Joe Biden, former South Bend, Indiana, Mayor Pete Buttigieg and U.S. Sens. Bernie Sanders and Elizabeth Warren have all led at one point. Sanders led the last Iowa Poll, with the three others clustered tightly behind him.
