From the perspective of late-night joke writers, there's really only one person running for United States president.
A staggering 97 per cent of the jokes Stephen Colbert and Jimmy Fallon told about the candidates in September targeted President Donald Trump, a study released today found.
That's 455 jokes about Trump and 14 about Democrat Joe Biden, according to the Centre for Media and Public Affairs at George Mason University. That doesn't even count 64 jokes made about Trump's family or administration, the study said.
"When Trump's onstage, everyone else is blacked out," said Robert Lichter, communication professor at George Mason.
He's been studying late-night humour and politics since 1992. Republicans are usually targeted more than Democrats by the comedy writers, but the difference has never been this stark. The closest was the 2016 campaign, when Trump was the punchline for 78 per cent of the jokes to Hillary Clinton's 22 per cent, the centre said.
