Donald Trump wins Michigan, Missouri, Idaho caucuses in march to Republican nomination
- The ex-US president has won every nominating contest so far by wide margins, and is on track to lock down the party’s presidential nomination by mid-March
- His victory signals trouble for rival Nikki Haley, who has vowed to stay in the race until Super Tuesday

Donald Trump on Saturday easily won the Republican caucuses in Michigan, where the party has been riven by infighting that some Republicans fear could hurt his campaign in the key battleground state as he gears up for the general election in November.
The former US president also won the Missouri and Idaho Republican caucuses on Saturday, according to Edison Research.
In all three states, Trump trounced Nikki Haley, his last remaining rival for the Republican presidential nomination, moving him closer to becoming his party’s White House standard-bearer and a likely general election rematch with President Joe Biden, a Democrat.
In Michigan, Trump beat Haley in all 13 districts taking part in the nominating caucuses, according to the state Republican Party.

Overall, Trump won with nearly 98 per cent support: 1,575 votes to just 36 for Haley.
