WASHINGTON, United States (AFP) — Joe Biden hoped Kamala Harris would salvage his legacy as the man who saved America from Donald Trump. Instead, it lies in tatters.

The 81-year-old’s pride made him resist growing concerns about his age, health and mental acuity until it was too late, and a disastrous debate against Trump forced him to drop his bid for a second term barely three months before Election Day.

Biden cast the decision as a move to “pass the torch” to a new generation of leadership in the form of his vice president, whom he endorsed as the new Democratic nominee.

Had Harris won, the rows over his age and refusal to bow out earlier would have been forgiven by the Democratic Party.

Biden would have been able to celebrate a list of achievements in his one term that included guiding the country out of the Covid crisis, passing historic legislation, building infrastructure and promoting green energy.

On the foreign front he helped Ukraine’s fight against Russia’s invasion and hoped, against hope, that he could still end Israel’s conflict in Gaza.

US presidents famously always have an eye on the way they will be judged by history, and it was therefore in his interest that Harris should win against Trump.

Harris was “very much a legacy project,” for Biden, said Frank Sesno, a professor at George Washington University and former White House correspondent.

But Democrats are now likely to judge Biden far more harshly.

His bid for a second term was “perhaps a little bit of arrogance, or over-reaching,” Alex Keena, an associate professor of political science at Virginia Commonwealth University, told Agence France-Presse.

Back in 2020, Biden had run on a promise to be a transitional president, but his decision to seek four more years meant that when he dropped out there was no time for a proper primary to find a replacement.

“It was a missed opportunity for the Democrats to nominate someone with broad appeal,” said Keena.

“Granted, they might have nominated Kamala Harris... but as a result, the country didn’t get a chance to really know Kamala Harris or see her fight for the Democratic base.”
