Biden’s health is a worry for Republicans and Democrats in tonight’s debate

Tonight, Donald Trump and Joe Biden face each other in the first of two presidential debates. With about ten per cent of the electorate undecided, the debate – the first between a current and a former president – could change the momentum of the race.

Both candidates want to debate. Trump thinks he can trounce the rival he has often dubbed ‘Sleepy Joe’. Biden, a doddery octogenarian, urgently needs to persuade voters he is not too frail for office.  

Debating against a much more dynamic candidate might seem like a risk for Biden. But in fact, it’s a good idea. Trump is ahead in the polls, and the perception is that the president is weak. Biden has to change the narrative, and a televised showdown gives him the opportunity.

Both parties are worried. And, paradoxically, they are both worried about Biden’s performance. The Democrats’ concern is that the public will see Biden’s mental and physical decline.
