Will Joe Biden run for president in 2028?

Joe Biden is not constitutionally barred from running for president in 2028. The 22nd Amendment states that no person shall be elected to the office of president more than twice. Biden was elected to the presidency once -- in 2020 -- which means he has one elected term on record and would have the right to seek a second. Having served that single term from January 20, 2021, through January 20, 2025, he satisfies none of the triggers that would bar him under the Amendment. His prior eight years as vice president do not count toward the presidential term limit. The constitutional bar that prevents Donald Trump from running in 2028 -- two elected terms -- does not apply to Biden.

Age is the dominant practical factor in any Biden 2028 analysis. Biden was born November 20, 1942. He is 83 years old as of mid-2026 and would be 86 years old on Inauguration Day, January 20, 2029. No U.S. president has ever been inaugurated at age 86; Biden was already the oldest president in American history when he took office at 78 and left at 82. Beyond the age factor, Biden stepped aside from the 2024 presidential race, endorsing Vice President Kamala Harris, and as of mid-2026 has given no public signal of interest in a 2028 campaign. He has not filed with the Federal Election Commission, formed a campaign committee, or set any public decision timeline for 2028.

Biden's home state is Delaware, which carries 3 electoral votes and is classified as Safe Democratic, having voted Democratic in 2016, 2020, and 2024. Delaware's 3 electoral votes are among the smallest in the country. A Delaware-based presidential candidate would not add a competitive swing state to the Democratic ticket; the vice-presidential pick would need to supply battleground credibility from states such as Pennsylvania (19 electoral votes), Georgia (16 electoral votes), North Carolina (16 electoral votes), Michigan (15 electoral votes), Arizona (11 electoral votes), or Wisconsin (10 electoral votes). No major tracked 2028 Democratic presidential candidate shares Delaware residency with Biden, so a same-state 12th Amendment constraint is not a concern for a potential Biden candidacy.

The 2028 Democratic field has moved forward without Biden as a factor. As of mid-2026, the leading Democratic contenders in primary polling and prediction markets include Gavin Newsom (Governor of California), Kamala Harris (former Vice President), Pete Buttigieg (former Transportation Secretary), Alexandria Ocasio-Cortez (U.S. Representative), and Josh Shapiro (Governor of Pennsylvania). Biden is tracked as passed in the 2028 field -- not because a constitutional bar applies, but because he has given no indication of a 2028 campaign and the age question is a near-universal concern among analysts. His influence in the 2028 Democratic primary is expected to come through endorsement rather than candidacy.
