Donald Trump's grip on Republican politics is put to the test in ice-cold Iowa's caucuses

DES MOINES, Iowa (AP) — Voting is set to begin Monday night in icy Iowa as former President Donald Trump eyes a victory that would send a resounding message that neither life-threatening cold nor life-changing legal trouble can slow his march toward the Republican Party's 2024 nomination.

The Iowa caucuses, which are the opening contest in the months-long Republican presidential primary process, begin at 8 p.m. EST. Caucus participants will gather inside more than 1,500 schools, churches and community centers to debate their options, in some cases for hours, before casting secret ballots.

While Trump projects confidence, his onetime chief rival, Florida Gov. Ron DeSantis, is fighting for his political survival in a make-or-break race for second place. Former U.N. Ambassador Nikki Haley, the only woman in the race, stands in DeSantis' way. The two have competed aggressively in recent weeks to emerge as the clear alternative to the former president, who has alienated many Americans and could end up being a convicted felon by year’s end.

"I absolutely love a lot of the things (Trump) did, but his personality is just kind of getting in his way,” said Hans Rudin, a 49-year-old community college adviser from Council Bluffs, Iowa. He said he supported Trump in the past two elections, but will caucus for DeSantis on Monday.
