Florida Gov. Ron DeSantis said the result from tonight's Iowa caucuses will create a clear, binary choice for voters in the Republican primary.

“I think people are going to say there's only two possible nominees: Donald Trump or Governor DeSantis,” DeSantis told CNN’s Dana Bash at his campaign headquarters in Urbandale, Iowa.

“We’re the only ones that have strong support amongst bedrock Republican conservative voters, and to win a Republican nomination, you have got to be able to do that. I think Iowa will show that very clearly,” he said.

“A lot of these voters that are still undecided, it's almost all decided between Trump or me in terms of what they're doing, and I think that's just kind of where the party is and I think that will be apparent,” DeSantis continued. 

In the latest Des Moines Register/NBC News/Mediacom Iowa poll, former South Carolina Gov. Nikki Haley sits in between Trump and DeSantis at 20%. 

DeSantis urged voters considering Haley to caucus for him, arguing “Nikki Haley could not possibly beat Donald Trump. She doesn't have enough support amongst core conservatives.”
