The veteran Democrat is expected to face constant and fierce scrutiny over his age, said observers. He would be 86 by the end of a second term.
Some critics are unsure why Mr Biden, who called himself a bridge to future Democratic leaders during his 2020 campaign, is not ready to hand over the reins just yet.
“Joe Biden is not popular, but the Republicans are sort of seen as extreme, at least Donald Trump’s faction of the Republican Party,” Mr Coleman, a political cartographer, told CNA’s Asia First on Wednesday.
A recent poll showed that Mr Biden’s public approval fell to 39 per cent this month, nearing the lowest level of his presidency, as the US economy showed signs of losing steam.
However, Professor Gordon Flake, founding chief executive officer of the Perth USAsia Centre at The University of Western Australia, said that is “kind of par for the course for presidents” at this stage of their presidency.
“Ultimately, elections are about choices. They’re really not about approval ratings,” he added.
