On Sunday, Republican presidential candidates held their final events in Iowa ahead of the caucuses.

From former Ambassador to the U.N. Nikki Haley’s pictures with the Iowa State Fair Butter Cow – to Florida Governor Ron DeSantis’ visit to the Field of Dreams in Dyersville, candidates have held events across Iowa for the last year. 

"I'm going to use every minute I can to be able to win votes," DeSantis said at an event last week in Ankeny, IA.

Between all of the town halls and diner visits, some voters were still unsure of who they plan to support on the eve of caucus night.

"I've kind of narrowed it down to Haley and DeSantis," Retired U.S. Army Reserves Col. Mike Treinen said. 

Treinen served during the Vietnam War and says veterans' issues are important to him.

"With Iran and Israel, those are heavy duty issues," Treinen said. "There are a lot of people who would like to think that we're already at war with Iran."

He is also concerned about national defense and the crisis at the southern border. He wants a candidate who can beat President Joe Biden.

"I will not vote for Biden under any circumstances," Treinen said. "I think he just shows a complete failure of leadership, trying to always duck the issue, blame it on somebody else. A lot of poor ideas, the pullout from Afghanistan, the runaway inflation, the border."
