Iowa's cold wave a shock to Florida U.S. Senator Marco Rubio

Republican Presidential candidate Marco Rubio greets Collyn and Renee Bridges of Decorah, while Scott Carlson of Decorah looks on

Before Republican Presidential candidate Marco Rubio spoke at Decorah's Hotel Winneshiek at 7:15 Monday morning, he flew into Mason City's airport, landing at 3:30 a.m.

At that hour, Iowa's cold wave was a shock to the Florida resident.  "I need coffee," he told the morning audience in Decorah.  He joked that when he heard what the temperature was, he asked his campaign staffers, "That's in Celsius--right?"
