80-year-old United States President Joe Biden has officially launched his campaign for re-election in 2024.

Biden formally made his intention to become the Democratic frontrunner in a race that could pit him for a second time against Republican contender Donald Trump known on Tuesday, April 25, 2023.

The announcement came on the fourth anniversary of his first successful presidential bid, launched on April 25, 2019.

“Every generation has a moment where they have had to stand up for democracy. To stand up for their fundamental freedoms. I believe this is ours,” he tweeted.

“That’s why I’m running for reelection as President of the United States. Join us. Let’s finish the job.”

He tagged his campaign: “Let’s finish the job.”

After a series of big legislative wins and momentous foreign policy struggles in his first two years in office, Biden has no real challenger from within the Democratic Party.

But in a campaign that may result in a rematch of the 2020 election against Donald Trump, he is expected to face constant and fierce scrutiny over his age.

The veteran Democrat would be 86 by the end of a second term. Even if a medical exam in February found him “fit” to execute the duties of the presidency, many including in his own voter base believe he is too old.

He faces a smooth path to winning his party’s nomination, with no serious Democratic rivals. But he is still set for a hard-fought struggle to retain the presidency in a bitterly divided nation.
