Trump tells his supporters in Iowa to go out and caucus for him no matter the cost: If you die “it’s worth it.”

Trump brags about his "POLE NUMBERS" ahead of New Hampshire primary.

Donald Trump is urging his supporters to go out and caucus no matter the cost, even it’s their life.

A dangerous Arctic blast has moved into the central US this weekend and will lasts through early next week. Monday, the day of the caucuses, is expected to be the coldest January day for Iowa in at least five years, with wind chills as low as -40 degrees Fahrenheit, according to CNN. 

At a rally in Indianola, IA Sunday, Trump urged his supporters to go out and caucus even “if you’re sick as a dog.”

“You can’t sit home!” Trump said, according to a clip highlighted by Mediaite. “Even if you vote and then pass away, it’s worth it remember.”

Officials are warning that frostbite can occur within 10 minutes of outdoor exposure without proper winter clothing. This is fueling concerns among the candidates that the freezing temperatures could negatively impact turnout.

The last poll out of Iowa before the caucuses shows Trump with a commanding lead over former U.N. Ambassador Nikki Haley and Florida Gov. Ron DeSantis.

48 percent of Republican voters are planning to select Trump as their first choice for president, 20 percent plan to choose Haley and 16 percent say DeSantis is their first choice.

Among the top three candidates, Haley is facing a massive enthusiasm gap. Only 9 percent of those who said their minds were made up for Haley were “extremely enthusiastic” about supporting her at the caucuses tomorrow.
