The Associated Press, Fox News, CNN, CBS News and NBC News all called the caucuses for Trump at around 7:30 p.m. Monday night, just a half-hour after the caucuses were scheduled to start.
Many of the more than 200 who showed up in snow pants and tuft-tipped winter hats at a caucus precinct location in Coralville were same-day Republican registrants, including several who came out specifically to support Nikki Haley. The former South Carolina governor won Johnson County. It was the only county that Trump didn’t carry.
