DES MOINES, Iowa – They’re gonna freeze their caucuses off.

The state of Iowa will be more like “Ice Station Zebra” when hardy Republican voters head out to pick their presidential nominee Monday evening.

The forecast high for Des Moines is -4 degrees Fahrenheit Monday, according to Fox Weather, with temperatures dropping into the negative teens in the evening.

Add in the wind chill, and it could feel as low as a life-threatening 30 degrees below zero.

Despite the extreme elements that have forced the top GOP contenders to either cancel events or hold them virtually, the candidates — notably rivals of former President Donald Trump — are imploring voters to show up and caucus in the hope of dealing a blow to the front-runner.

Florida Gov. Ron DeSantis publicly admitted Thursday that he hoped the deep freeze would give him a boost due to his campaign’s Iowa infrastructure.

“With this weather, I think the organization is going to matter even more, because going out in negative-20 degrees, unless you’re really committed to voting, that’s an easy reason why you wouldn’t want to go,” DeSantis told Fox News’ Sean Hannity. “So we’ve got that in place.”

At an event Friday morning, the Florida governor predicted the caucuses turnout could be “much smaller” than in past years due to the elements, while reiterating Friday afternoon that “nobody can forecast what the turnout is going to be” and adding that hat it will be “a major wildcard.”

DeSantis has staked the hopes of his 2024 campaign on how well he does in Iowa, visiting all 99 counties and investing heavily in door-knocking.

The governor is continuing to hold multiple events per day in the hope of finishing as close to Trump as possible.

The 77-year-old former president, meanwhile is hoping to win by a historic margin Monday night, with his campaign organizing a “10 for Trump” caucuses commitment strategy targeting low-propensity participants — who may prefer to stay home and warm when the moment of truth arrives.

As if the cold wasn’t complicating the final days before the caucuses enough, Iowa was also hit by a major blizzard Friday, forcing the cancelation of a Trump event headlined by Arizona GOP Senate candidate Kari Lake.

Former South Carolina Gov. Nikki Haley cancelled all her in-person events on Friday but was still planning to hold virtual events with voters, while the pro-DeSantis super PAC Never Back down scrapped two events the Sunshine State governor was due to attend thanks to “unsafe weather conditions.”

“Stormy weather won’t stop us from ensuring Iowans hear Nikki’s vision for a strong and proud America,” said Pat Garrett, Haley’s Iowa spokesperson. “With only three days until the caucuses, we’re going to keep telling voters why they should pick Nikki.”

Haley is still hoping to get a good showing Monday night, asking voters in Ankeny, Iowa to “tell 10 people” about the caucuses and “bring people” along with them to their local caucus site.

DeSantis and Haley are currently battling for second place in the polls and are fighting to be the No. 1 alternative to Trump.

Per RealClearPolitics, the former president is averaging 53% support while Haley has 17.8% and DeSantis has 15.5%.
