For now, a rerun of the 2020 race looks almost certain. With months to go till the first primaries, who is best placed to win?

Republican and Democratic voters have to wait nearly a year to decide on their candidates, but the US's 2024 presidential election campaign is already well underway.

So far, the odds are in favour of a head-to-head race between Joe Biden and Donald Trump, the first election since 1892 to pit a former president against a sitting one. So what can we expect, and who might come out on top?

Biden officially launched his reelection bid last month, rallying Americans to join him with a new slogan: "let’s finish the job". Meanwhile, on the other side, polls, fundraising numbers and endorsements all seem to point one way: while he already faces primary challengers as well as serious legal problems, Trump is set to win the Republican nomination.
