'Promise?’: Biden campaign mocks Trump for saying he will leave country if he loses election

‘Could you imagine if I lose?’

In a campaign ad on social media, Joe Biden has taken up Donald Trump’s frequent campaign rally tease that he won’t return to a number of US states – or leave the country entirely – if he loses his re-election bid.

Above a video compiling his remarks, Mr Biden wrote: “Promise?”

“I may never have to come back here again if I don’t get Iowa," the president told a rally crowd in the state. "I’ll never be back."

At a rally in Minnesota, he told the crowd that if he loses, "I’m never coming back.

He made similar remarks in Ohio, Florida and North Carolina.

Wih less than three weeks so Election Day, the president told supporters in Georgia that he “won’t feel so good” if he loses to his Democratic rival.

“Could you imagine if I lose?” he told rallygoers on 16 October. “I’m not going to feel so good. Maybe I’ll have to leave the country. I don’t know.”

The president is trailing in national polls and has less campaign cash than the former vice president, who raised $383m over the last month along with affiliated Democratic organisations.

“I could raise more money,” the president said in Georgia. “I would be the world’s greatest fundraiser, but I just don’t want to do it.”

The former vice president has also outspent the president’s re-election campaign by nearly two-to-one across television advertising over several months.

Within the last month, in battleground states Michigan, Pennsylvania and Wisconsin, which election analysts believe either candidate will need to win to secure the presidency, Mr Biden has spent roughly $53m compared to the president’s $17m, according to Advertising Analytics.
