Former President Donald Trump maintains a commanding lead among Republican candidates with the countdown well and truly on until the Iowa caucuses.
US Studies Centre Director of Research Jared Mondschein says it would be “unprecedented” for Donald Trump to end up not winning the Republican nomination.
“No one has gone on to lose the nomination given the lead that he has,” Mr Mondschein told Sky News Australia.
“At this point, it is all but a surefire thing that he will win the nomination.”
Mr Mondschein said there is a lot of “intrigue” surrounding who the former president will select as his vice president.
