With President Joe Biden's recent withdrawal from the 2024 presidential race, Donald Trump has now become the oldest presidential candidate in U.S. history at 78 years old. Democrats, including presumptive nominee Kamala Harris, are leveraging concerns about Trump's age and fitness for office, with Harris's campaign highlighting that the American people are 'rightly concerned' about Trump's candidacy. Medical experts suggest that transparency regarding medical records would benefit voters, especially given Trump's recent health incidents, including an assassination attempt that left him injured. Critics, including former Obama advisor David Plouffe, have pointed out Trump’s performance at the Republican National Convention as indicative of decline, raising questions about his cognitive abilities. Polls indicate a lack of enthusiasm for a Biden-Trump rematch, and Trump's age is likely to play a significant role in shaping the campaign narrative. As the election approaches, both candidates will face scrutiny over their age and health, with Trump needing to address these concerns effectively.
