With Iowa's presidential caucuses just one day away, Republican candidates are making their final push to secure support from voters in this crucial leadoff voting contest. The latest Des Moines Register/NBC News poll reveals that former President Donald Trump maintains a significant lead with the support of nearly half of likely caucusgoers. Nikki Haley, the former U.N. ambassador and South Carolina governor, and Ron DeSantis, the Florida governor, are in a close battle for second place.

Braving bone-chilling temperatures and blustery winds, Trump, Haley, and DeSantis are traversing the state to appeal to voters on the eve of the caucuses. However, adverse weather conditions force Haley to cancel an in-person campaign stop, highlighting the challenges faced by candidates during this crucial period.

Despite being less visible on the campaign trail this week, former Governor Asa Hutchinson of Arkansas focuses his efforts on Iowa, seeking to exceed expectations in the caucuses. Hutchinson, who qualified for the first Republican candidate debate but fell short in subsequent debates, remains determined to make an impact in this critical contest.

One supporter of DeSantis, Hans Rudin, cites the Florida governor's swift response to the Oct. 7 attack on Israel by Hamas as a deciding factor in his endorsement. In light of Rudin's support, he clarifies that he would still back Trump if the former president becomes the Republican nominee, indicating the lasting loyalty among some supporters.

Meanwhile, Trump urges his supporters not to let anything deter them from voting, even if they are "sick as a dog." He emphasizes the significance of their vote, underscoring the importance of active participation in the caucuses.

As the candidates rally across the state, evidence of the recent snowstorm's impact can still be seen, with wrecked vehicles stranded in medians and near roads. Bone-chilling temperatures add to the challenging conditions, with Des Moines experiencing a high near minus-9 degrees Fahrenheit (-23 Celsius) and a wind chill making it feel as cold as minus-30 Fahrenheit (-34 Celsius).

During Trump's rally, protests briefly interrupted his speech, albeit for the first time in years. Trump responded swiftly, dismissing the protesters and emphasizing his youthfulness and maturity compared to theirs. The incident adds an element of excitement, reminiscent of the disruptions that marked his campaign events in 2016.

Amid the campaign stops and cancellations, Judy and Brad Knowler, two Iowa voters, share their concerns about truly understanding the candidates amidst the debates and negative political ads. They express a desire to see the real person behind the campaign façade before making their final decisions.

In his only Iowa rally this weekend, Trump delivers a fiery message, calling on supporters to use the caucuses as an opportunity to fight back against the so-called Washington swamp. He urges voters to assert their voices and vote, promising to reclaim the country from what he perceives as deceit and wrongdoing.

With the caucuses just hours away, the stakes are high for Republican presidential candidates, who are vying for a strong showing in Iowa to set the tone for the rest of the primary season.
