AP defends decision to call Iowa caucuses for Trump in 30 minutes

• Voters were turning out despite the record cold weather for the caucuses, which one precinct captain called "frozen nostril cold."

Driving the news: The news organization said the projection was based on an analysis of early returns and voter survey data from eight counties.

• Those counties showed Trump with an "insurmountable lead," AP said.
• And those rural counties were "demographically and politically similar" to many still left to report, it wrote Monday evening.

Zoom in: Members of Florida Gov. Ron DeSantis' campaign accused the media of "election interference" for calling the race before many voters had voted.

• At the Sheraton Hotel in West Des Moines, DeSantis supporters told Axios the call was unfair.
• "It's ridiculous. It's bad narrative and makes the media look irresponsible. Let the system work," says Jake Highfill, an Iowa representative and DeSantis supporter.

Zoom out: AP was not alone in its early call. Fox News, NBC News and CNN all projected a Trump win before 9pm ET.

The other side: "The people of Iowa sent a clear message tonight: Donald Trump will be the next Republican nominee for President," Alex Pfeiffer, communications director of Make America Great Again Inc., said in a statement.

• "It's time for Nikki Haley, Ron DeSantis and Vivek Ramaswamy to face reality and stop wasting time and resources," he continued.
