be a two person race in new hampshire. >> reporter: the candidate with the most stake, florida governor ron desantis. >> are you ready to brave the cold and make your voice heard tonight? reporter: desantis staking his entire campaign on iowa, holding more events here than haley and trump combined. >> we went out to earn your vote. we went out to all 99 counties, we answered questions, we showed up to debates. >> reporter: one thing he didn't do, aggressively take on the frontrunner. desantis conceding trump's indictments helped the former president. our whit johnson pressing the governor, should he have hit trump harder? >> do you think that has held back your campaign or hurt you in any way? >> we started off the first week or two very strong, and we were getting good media. then he got indicted in florida with that, and that just that wiped everything else off the screen, and then he got indicted again in d.c., and then again in atlanta, and so that just subsumed, i think, the whole process at that point.
