In a pivotal moment for President Joe Biden's legacy, voters will soon decide the fate of his administration's accomplishments as Vice President Kamala Harris steps into the role of Democratic standard-bearer. With former President Donald Trump posing a threat to Biden's achievements, the success of Harris's electoral campaign will play a vital role in how this single term presidency is remembered.

On Wednesday night, President Biden will address the nation from the Oval Office, discussing his decision to step aside and the future that lies ahead. This speech presents an opportunity for Biden to make a compelling case for his legacy, which includes sweeping domestic legislation, renewed alliances abroad, and a steadfast defense of democracy.

Biden's endorsement of Harris immediately after announcing the end of his candidacy has given her a head start over potential challengers and has jumpstarted a campaign focused on continuing the administration's agenda. Presidential historian Lindsay Chervinsky believes that if Harris emerges victorious, it will confirm that Biden made the right decision to fight against the threat posed by Trump. Biden will be seen as a legend for democracy. However, if Harris were to lose, questions may arise about the timing of Biden's decision and the effectiveness of the Democratic Party's strategy.

While every presidency invites speculation about alternative scenarios, Biden's late submission to his party's crisis of confidence heightens the stakes. Drawing a contrast to the past, Harris has consistently praised Biden and his accomplishments over the last three years, making any attempt to distance herself difficult to explain. Furthermore, she must rely on the existing Biden political operation to secure victory in the election, with just over 100 days remaining until the polls close.

Despite Trump and his allies attempting to tie Harris to Biden's record, labeling her as "Biden 2.0," Biden's loyal supporters argue that his place in the history books remains intact. Throughout the campaign, the president has reassured his former staffers that he is not going anywhere, promising to be involved in campaign events and fundraisers benefiting Harris, albeit at a slower pace compared to if he were on the ballot himself.

As advisors strategize on how to deploy the president in support of Harris's campaign, Biden's popularity, once questioned by voters on both sides of the political spectrum, could play a crucial role. Ultimately, the outcome of the election will determine how history remembers Biden's legacy, with his achievements and the continuity of his agenda hanging in the balance.
