As the Democratic candidate for the upcoming general election, Joe Biden is unlikely to be replaced. Unless he voluntarily steps down or becomes physically unable to run for president, he will likely remain the candidate. At this time, it is difficult to envision a viable candidate other than Biden.
In the event that Biden does step down, Democrats would face a challenge in choosing a new candidate. While waiting for the results of the primaries, Biden has built up significant support for his campaign. Conversely, a late entry candidate would not be viable at this stage.
Despite the possibility of retirement, convincing Biden to do so won’t be easy. He would need to leave the race on his own terms and with dignity. His announcement would need to wait until after the primaries, which end on June 4. If he were to retire, a new battle for his replacement would begin among potential successors.
Kamala Harris is a potential candidate but may face resistance due to questions about her ability to inspire confidence. Other potential candidates like governors Gavin Newsom and JB Pritzker are in positions to leverage the situation to their advantage.
If Biden were to leave the race at a late date, Democrats would be faced with serious logistical challenges as early voting has already begun in some states and they would have to select a new nominee quickly.
Both parties are facing similar challenges as Donald Trump, who is also approaching election age limitations and has faced legal issues that could affect his eligibility to run for president. Ultimately, due to weakened national parties, there are few candidates of stature who could easily replace either Biden or Trump. Both parties have few mechanisms to sway their candidates from continuing their campaigns.
