Campaign events are falling as swiftly as the Iowa snow as wintry weather hampers Nikki Haley, Ron DeSantis and former President Donald Trump's schedules ahead of Monday’s leadoff presidential caucuses. Prolonged freezing temperatures, combined with strong winds, foreshadow possibly life-threatening conditions on the night that Republican voters will gather to make their pick for their 2024 nominee. Iowans are accustomed to the cold, though the latest winter wave and low temperatures could mean unprecedented conditions for caucus night itself. Early into next week, forecasters said significant winds would make things feel as cold as 45 degrees below zero, a record-breaking forecast that could keep potential voters at home.
