Former United States president Donald Trump on Monday night won the Iowa Republican caucuses by an unprecedented margin.

Trump, who kickstarted his bid to win the party’s presidential nomination, cruised to an easy victory in the lead off contest in the 2024 Republican presidential nominating calendar.

He exceeded expectations and shattered contested caucus records, securing more than 50 per cent of the vote.

“We want to thank the great people of Iowa,” Trump said in a caucus victory speech.

Both Florida Governor Ron DeSantis and former UN Ambassador Nikki Haley finished second and third, respectively, at roughly 20 per cent.

Meanwhile, Vivek Ramaswamy garnered roughly 8 per cent support among caucus goers and has also suspended campaign, throwing his support behind Trump.

The former President also congratulated DeSantis, Haley and biotech entrepreneur Ramaswamy for their performances, describing all three as “very smart people, very capable people.”

The results in Iowa showed how devoted Republicans remain to Trump amid his highly unusual campaign waged between court appearances as he battles four indictments.
