Republican presidential candidates are gearing up for a final day of campaigning in Iowa, where Donald Trump is the overwhelming favorite to secure the first victory of the 2024 campaign. While the former president's position has cemented him as the top contender, the battle for second place is heating up, with candidates like Florida Governor Ron DeSantis and former UN Ambassador Nikki Haley vying for a strong runner-up finish.

I’m so excited to be heading to Iowa today to campaign for President Trump ahead of his historic victory tomorrow in the Iowa Caucuses.

A commanding victory for Trump in Iowa would strengthen his claim as the only viable candidate to take on Democratic President Joe Biden in the November election, making it a critical contest for his challengers. DeSantis, in particular, has invested heavily in Iowa, with the outcome of the caucus potentially determining the fate of his campaign. Despite the life-threatening cold that has forced campaign events to be canceled, all eyes are on the caucus meetings that are set to begin at 7 p.m. CST (0100 GMT on Tuesday).

The bone-chilling temperatures may impact voter turnout, with Iowa's large evangelical population and historically conservative values adding another layer of complexity to the race. As Iowa takes center stage in the lead-up to the 2024 presidential election, the results of the caucus are poised to set the tone for the rest of the Republican primary season. Trump's lead in national polls and his unwavering support among his loyal base may give him a significant advantage, setting the stage for a contentious battle for the nomination in the months to come.
