On April 25, 2023, President Joe Biden formally announced his intention to run for re-election. Ending speculation, he said that he planned on keeping Vice President Kamala Harris as his running mate. The announcement led to Republicans upping their attacks on Harris, especially blaming her for problems at the border with the large numbers of illegal immigrants crossing into the United States. Biden had asked Harris to quarterback that issue, and Republicans argue that her assignment has done nothing to deal with this major campaign issue.
During late 2021, Biden was facing low approval ratings, leading to speculation that he might not seek re-election. Some Democrats in Congress such as Representatives Carolyn Maloney and Tim Ryan and former Representative Joe Cunningham publicly urged Biden not to run. There were concerns not only about Biden's unpopularity, but also about his age and any possible cognitive impairment as the result of it. Biden became the oldest person to assume the office of President at age 78 in 2017, and will be 82 at the end of his first term. If re-elected, he would be 86 at the end of his second term. According to an NBC poll released in April 2023, 70 percent of Americans believe Biden should not run for a second term. Among Democrats, 51% believe this to be the case. According to the FiveThirtyEight.com national polling average, Biden's current approval rating is 41 percent, and his disapproval rating is 55 percent.
There had been speculation that Biden may face a primary challenge from a member of the Democratic Party's progressive faction. But when the Democrats outperformed expectations in the 2022 midterm elections, many believed the chances that Biden would run for and win his party's nomination had increased.
Even before Biden had formally announced his intention to seek a second term, Author Marianne Williamson announced her candidacy in February 2023. She had previously sought the Democratic presidential nomination in 2020. The most prominent challenger to Biden from within the party has been Robert F. Kennedy Jr. who announced his candidacy for the nomination in April of 2023. But on October 9, 2023, Kennedy announced that he would be dropping out of the Democratic primary and would run as an independent candidate instead. Another challenger for the Democratic Party's presidential nomination was Representative Dean Phillips who announced his challenge of Biden on October 26. But on March 6, 2024, Philips suspended his campaign after failing to win any primaries the previous night on Super Tuesday.
On March 12, 2024, Biden officially became the presumptive Democratic presidential nominee. He has won an estimated 3,073 delegates. The only other candidate to win any delegates for the Democratic Party is entrepreneur Jason Palmer who won the Democratic Primary in American Samoa, along with it's 3 delegates.
