SIOUX CITY, IOWA — Former President Donald Trump was supposed to fly into this city in northwestern Iowa to give a rally at the charming Orpheum Theater downtown on Saturday night, but the sub-zero temperatures, high wind, and a few inches of snow on the ground convinced him to cancel.

Because I had spoken to many caucus-goers undecided between Trump and Florida Gov. Ron DeSantis, I thought DeSantis’s Sunday night meet-and-greet at Beer Can Alley on 4th Street would be a great opportunity for him to win over some Trump leaners. But on Saturday night, DeSantis canceled his Sioux City event for Sunday.
