Donald Trump turned 78 on June 14, 2024, a birthday he has said he wishes "the day doesn't exist." Trump would be the oldest president ever inaugurated at 78 years and 219 days if elected in 2024, surpassing Joe Biden's previous record. At his rallies, Trump mocks Biden's cognitive abilities and shares edited clips to highlight this, despite experiencing his own verbal mishaps. Trump and Biden, born three years apart and raised in the post-WWII era, share similar backgrounds including avoiding Vietnam War service and being grandparents. In the rematch between the two oldest presidents, over half of U.S. adults believe both are too old for another term, a sentiment that has increased by 10 points from last year, according to an ABC/Ipsos survey.
