Diaz-Balart is the longest-serving member of the Florida congressional delegation, first elected in 2002. He is the son of Cuban refugees and a founding member of a caucus for Hispanic Republicans. He defeated Democrat Joey Atkins. The Associated Press declared Diaz-Balart the winner at 7:17 p.m. EST.
