Today, Tuesday, US President Joe Biden officially announced his 2024 election campaign, thus running for a new term in the elections scheduled for November next year, and Biden is the oldest president in the history of the United States.

In a video titled "Freedom," Biden reiterated his 2020 campaign message, which is "fighting for the soul of our nation, uniting the country, and supporting the middle class," adding, "When I ran for president 4 years ago, I said we were in a battle for the soul of America, and we still are. The time to be satisfied has not yet come, so I am running for re-election."

The video began with footage of the protests that took place at the US Capitol on January 6, 2021, carried out by supporters of former President Donald Trump to refuse to certify the results of the 2020 presidential election, which was won by his rival Biden.

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.

That’s why I’m running for reelection as President of the United States. Join us. Let’s finish the job. https://t.co/V9Mzpw8Sqy pic.twitter.com/Y4NXR6B8ly

President Biden, 80, says in the video that "personal freedom is fundamental to us Americans, there is nothing more important and sacred than it," adding, "This was the work of my first term: to fight for our democracy," according to Fox News.

Biden has called Republican Party platforms threats to American freedom and pledged to fight efforts to reduce women's health care benefits and cut Social Security spending.

Biden's approval rating remained at just 39 percent in a Reuters/Ipsos poll on April 19, and some Americans are deeply concerned about his age.

If he wins, he will turn 86 at the end of his potential second term, about a decade more than the average age of men in America. Americans have never elected a president of such an age, nor has a candidate ever asked him to be given a new term in the White House until he is 86.

Three challenges

US President Biden's path to the presidency again next year looks full of major challenges, from reassuring his age, to containing the many geopolitical threats, to preparing to face a Republican opponent who may not be Donald Trump.

Two medical examinations in November 2021 and February 2023 concluded that he was "in good health" and that he was "qualified" to exercise his duties.

But Joe Biden, accustomed to jerky rhetoric, prone to lapses and showing signs of age, should expect an uptick in Republican attacks focused on his health and mental state.

Joe Biden has never hidden that he would prefer to face Trump in the next presidential ballot, because he has already defeated him, and because Trump will have to reconcile his electoral agenda with facing the prosecution he faces.

But candidate Biden must adapt his campaign if another challenger emerges who is younger or more moderate, such as Florida Governor Ron DeSantis.

Externally, an escalation with Beijing, for example, over Taiwan before the presidential election could affect the campaign of Biden, who has built all his foreign policy on competition with China.
