Tonight's first U.S. presidential debate between Donald Trump and Hillary Clinton is a study in personality clashes. Both candidates share popularity woes (55 per cent unfavourablity for Clinton; 59 per cent for Trump, according to a new ABC News/Washington Post poll). Clinton leads Trump by just 2.5 percentage points, according to the RealClearPolitics national polling average. Billionaire businessman and reality TV star Mark Cuban was rumoured to be considered as a possible stand-in for Donald Trump during mock debates to prepare Hillary Clinton. "A third scenario is a Jekyll and Hyde," he says, suggesting Clinton might benefit from practising with "multiple Trump stand-ins."
