Why did the Iowa Caucus mark the end for DeSantis? 12:15

On Deadline is making its way to the middle of the country as we look at the Iowa Caucus and what the results mean for Republican hopefuls. Former President Donald Trump proved the polls right on Monday night, taking home the victory in Iowa. Florida Gov. Ron DeSantis came in a distant second -- what did that really mean for the future of his campaign? 'On Deadline' is hosted and produced by Lauren Barry. It's also produced by Joe Hiti, Christy Strawser, Bill Smee and Myron Kaplan. Sound design by Joe Hiti.
