Background and path to power
Joe Biden spent 36 years as a U.S. senator from Delaware and eight years as Barack Obama's vice president before winning the presidency in 2020. His appeal centered on experience, stability, and a promise to restore normalcy after a turbulent period.
Donald Trump came from business and television with no prior political or military office — highly unusual for a president. He won in 2016 as a political outsider, lost in 2020, and then won again in 2024, becoming only the second president (after Grover Cleveland) to serve two non-consecutive terms.
Party and political style
The two men anchor opposite ends of American politics. Biden governed as a center-left Democrat who generally worked through institutions, alliances, and legislation negotiated with Congress. Trump governs as a populist Republican who favors bold executive action, direct communication with supporters, and a willingness to break with political norms. Supporters see Trump's style as decisive and disruptive in a good way; critics see it as norm-breaking and destabilizing. Supporters see Biden's style as steady and institutional; critics saw it as slow or ineffective.
The economy
Both presidents can point to economic strengths, and both faced criticism.
Under Biden, supporters highlight strong job creation, unemployment falling below 4% for an extended stretch, and major investment laws. Critics point to the sharp inflation of 2021-2023 and high prices, which polling suggested overshadowed the job gains in voters' minds. Biden's signature economic measures included the American Rescue Plan (a $1.9 trillion pandemic-relief package), a $1.2 trillion bipartisan infrastructure law, and the CHIPS and Science Act to boost domestic semiconductor manufacturing.
Trump's economic approach centers on tax cuts, deregulation, and — especially in his second term — tariffs as both economic and negotiating tools. Supporters credit his first-term tax cuts and pre-pandemic growth; critics argue the tariffs raise consumer prices and that the benefits of tax cuts skew toward higher earners. (For detail, see our explainer on Trump's tariffs.)
Foreign policy
This is one of the clearest contrasts. Biden emphasized rebuilding alliances and multilateral cooperation: he rallied NATO behind Ukraine after Russia's 2022 invasion and stressed cooperation with traditional allies. Critics pointed to the chaotic 2021 withdrawal from Afghanistan as a major failure.
Trump follows an "America First" approach that is more skeptical of alliances and international institutions, favoring direct deal-making and a harder line on trade. His second term has featured assertive use of military force abroad. Supporters call this strength and independence; critics call it unpredictable and risky.
Immigration
Immigration divides them sharply. Trump has made border security and reduced immigration a defining priority in both terms, favoring stricter enforcement, more deportations, and physical barriers. Biden took a more moderate approach, though rising border crossings during his term drew heavy criticism and became one of his administration's biggest political vulnerabilities. Supporters of each frame the other's approach as either too harsh or too lax.
Domestic policy and legislation
Biden's domestic record leans on legislation passed through narrow Democratic majorities: infrastructure, climate and clean-energy investment, letting Medicare negotiate some drug prices (with a $2,000 annual out-of-pocket cap and $35 insulin for many on Medicare), gun-safety measures, and expanded veterans' benefits. Trump's domestic agenda emphasizes cutting taxes and regulation, reshaping the federal workforce, and reversing many of his predecessors' policies through executive action.
Judicial appointments
Both reshaped the courts. In his first term, Trump appointed three Supreme Court justices — shifting the Court's balance for a generation — and confirmed 234 federal judges. Biden confirmed 235 federal judges, appointing more women and more people of color to the bench than any prior president, and nominated Ketanji Brown Jackson, the first Black woman to serve on the Supreme Court.
The 2020 and 2024 elections
Biden and Trump ran against each other directly in 2020, which Biden won. A rematch was widely expected in 2024, but after concerns about his age and standing, Biden withdrew from the race in July 2024 and endorsed Vice President Kamala Harris. Trump then defeated Harris and returned to office — the pivot that produced the current presidency.
Age
Both are among the oldest people ever to hold the office. Biden, born in November 1942, left office in January 2025 at 82 — the oldest-serving president in U.S. history. Trump, born in June 1946, is about three and a half years younger, and became the oldest person ever inaugurated when his second term began in 2025.
Legacy — how history may judge them
It is too early for a settled verdict, especially with Trump's second term still in progress. Biden's defenders argue he delivered durable investments and steady leadership through crisis; his critics emphasize inflation, immigration, and the political defeat of his party in 2024. Trump's supporters credit him with reshaping the courts, the economy, and the terms of political debate; his critics raise concerns about norms, institutions, and polarization. As with most presidents, the final assessment will take years — and will depend heavily on how his second term ends.
