Donald Trump and his top aides will be closely monitoring Monday night’s Iowa caucuses as his White House transitions from a focus on impeachment to the likely bruising re-election fight.

The president has been keenly keeping tabs on the Democratic Party’s primary battle, focusing mainly on a small handful of top candidates – hitting them with personal attacks as he tries to discredit each of his would-be general election foes.

“I have to sit back and watch,” Mr Trump said over the weekend about the Democrats’ process. “I mean I’m watching and I have little nicknames for all of them,” he added, likely signalling he will take to Twitter as the results come in to try to knock down the Iowa winner a peg.
