Former White House chief of staff Mick Mulvaney exposes US President Donald Trump’s campaign strategies ahead of the midterms. Mr Mulvaney says Republicans are talking about anything to increase voter turnout. “Republicans are having a difficult time talking about the economy,” he told News24. “Right now, it’s the people who might vote for him that are a little lukewarm about going to the polls, and that’s what has Republicans frightened more than anything else.”
