President Joe Biden's unexpected withdrawal from the 2024 presidential race has sparked comparisons to the tumultuous 1968 Democratic National Convention, with Vice President Kamala Harris emerging as the frontrunner to replace him. Biden's decision, just over 100 days before the election, follows widespread concerns about his age and declining health, which have plagued his administration. While Biden's foreign policy achievements, such as supporting Ukraine against Russia and restoring NATO alliances, are acknowledged, his departure has raised questions about the Democratic Party's unity and chances against former President Donald Trump. World leaders, including Ukraine's President Zelenskyy and Israel's Prime Minister Netanyahu, have expressed gratitude for Biden's leadership, while GOP figures have called for his resignation if he is deemed unfit. The Democratic National Convention in August is anticipated to be crucial, with Harris likely receiving the support of most delegates but still facing potential challenges from other candidates. As the political landscape shifts, the implications of Biden's exit on both domestic and international fronts remain to be seen.
