In the aftermath of President Joe Biden's lackluster debate performance and concerns about his ability to effectively challenge former President Donald Trump in the upcoming November election, speculation is rife among Democrats about potential replacements for the presidential ticket. While the chances of President Biden stepping down are slim just four months before the election, discussions about alternative candidates have nevertheless begun to gain traction.

One obvious choice to replace President Biden is Vice-President Kamala Harris, who is already on the ticket. As the face of the administration's campaign to protect reproductive rights, Harris has emerged as a loyal ally to the President, fiercely defending his debate performance. Despite some initial criticism, Harris argued that the election should ultimately be about substance rather than style. However, she has struggled with low approval ratings throughout her tenure, with 49% of Americans disapproving of her performance, according to polls tracked by FiveThirtyEight.

Another potential candidate is Gretchen Whitmer, the two-term governor of Michigan. Whitmer, who has campaigned for Biden in the past, has been touted as a rising star in Midwestern Democratic circles. Having spearheaded a successful campaign that led to Democrats gaining control of Michigan's legislature and governor's mansion, Whitmer has enacted progressive policies such as protecting abortion access and implementing gun safety measures. While she has expressed her desire to see a Generation X president in 2028, she has refrained from suggesting that she may fill that role herself.

California Governor Gavin Newsom, a fierce surrogate for the Biden administration, is also on the list of potential replacements. Newsom has frequently appeared on cable news networks, lauding Biden's achievements. Known for his political ambitions, he has been considered a possible candidate for the 2028 presidential race. With his national profile raised through media appearances and a notable debate against Florida Governor Ron DeSantis, Newsom is seen as an appealing stand-in for President Biden.

Transportation Secretary Pete Buttigieg, who ran for president in 2020, is another name frequently mentioned. Buttigieg is recognized as one of the administration's most effective communicators and has successfully managed various public crises in his role as Secretary. His presidential aspirations are no secret, and his experience and crisis management skills make him a strong contender for a potential replacement.

Lastly, Governor Josh Shapiro of Pennsylvania has garnered high approval ratings since his election in 2022. Notably, Shapiro swiftly rebuilt a collapsed bridge on a crucial Philadelphia highway, earning him national attention and reinforcing his infrastructure credentials as a potential 2028 presidential candidate.

While the possibility of President Biden stepping down remains unlikely at this stage, Democrats are becoming increasingly anxious and uncertain about the future of his candidacy. As the election looms closer, the discussions surrounding potential replacements highlight the importance of finding the right candidate to face off against former President Trump in what promises to be a fiercely contested battle.
