"Potential Replacements for Biden on 2024 Democratic Ticket"

President Joe Biden's age and fitness have become a campaign issue, with 86% of Americans believing he is too old for another term. While no prominent Democrats have demanded Biden bow out, speculation about potential successors is growing. Possible contenders include Vice President Kamala Harris, Rep. Dean Phillips, and a group of blue-state governors. Other potential candidates, such as Pete Buttigieg, Michelle Obama, and Dwayne "The Rock" Johnson, may also be considered. The process of selecting a new Democratic nominee would be complex and messy.
