Heading into Iowa caucuses, Ron DeSantis says "a lot" of Iowans "haven't made up a final decision"

Washington — Florida Gov. Ron DeSantis, once widely viewed as the favorite to challenge former President Donald Trump for the GOP nomination, but now who appears to be battling Nikki Haley for second place, said his campaign feels "really good" heading into Monday night's Iowa caucuses. 

After months of betting big on the Hawkeye State, DeSantis is nodding to the returns he hopes to see on the investment, even as polls show Trump maintaining a dominant lead.

"When people take a poll, they can push someone one way or other, but there's a lot of people that still haven't made up a final decision," DeSantis told "CBS Mornings" anchor Tony Dokoupil. "So I think we're in good situation to be able to capture that."
