Donald Trump is "playing a foolish game, driven by vanity and arrogance", a top US political commentator has told talkRADIO after a week in which the Republican candidate for the presidency appeared to sanction the assassination of his Democrat rival Hilary Clinton and suggesting the incumbent president, Barack Obama, is the "founder of ISIS".
"He’s just throwing mud and hoping it sticks," The Independent's US digital editor Andrew Burncombe told Jonny Gould and Ash.
"A lot of his language is loaded. A few years ago he was part of the group saying Obama wasn’t born in the US but was born in Indonesia, or he was born in Kenya.
"He’s hired these advisors who keep trying to make him undergo a reset and be more presidential and go to the middle ground.
"Trump, by his own admission, can’t do this. He goes off message, like he did earlier this week when he suggested that shooting Hillary Clinton would stop her appointing [liberal] judges."
Despite his regular faux pas, Trump continues to draw support in the United States.
"He taps into two things: he’s different and he dares to be outside the system, to be rude, to speak his mind," Burncombe said.
"It taps into an anti-expertise phenomenon that seems to be popular, we saw it in the UK with Brexit.
“He’d love to be in the White House. But he’s playing a very foolish game, and a lot of it is driven by his vanity and arrogance. He refuses to listen.
“Whatever the outcome, his candidacy has caused damage that is going to take a long time to fix."
