For the 2024 U.S. presidential election, the field started out huge, but by Election Day it had narrowed to a relatively small number of serious contenders. Below is a clear rundown of the major names people usually mean when they ask “who’s running for president 2024,” plus a bit of how the race evolved over time.

Main 2024 presidential contenders

By the heart of the general-election season in 2024, attention had largely centered on the Democratic and Republican tickets, plus a handful of prominent third‑party and independent candidates.

Donald Trump Republican – nominee Former president who launched a comeback bid, dominated the GOP field, and became the Republican nominee in 2024.
Robert F. Kennedy Jr. Independent Environmental lawyer and vaccine‑policy critic who left the Democratic primary lane and ran as an independent, aiming to appeal to disaffected voters in both parties.

Jill Stein Green Party Long‑time Green Party figure who again ran on a platform centered on climate action, anti‑war foreign policy, and debt relief.

Major candidates who ran earlier, then exited

The 2024 cycle also featured a long list of candidates who launched presidential bids but dropped out before Election Day.

  • Ron DeSantis – Florida governor, once seen as Trump’s main Republican rival, formally entered the race in May 2023 but later suspended his campaign after underperforming in early contests.
  • Nikki Haley – Former South Carolina governor and U.N. ambassador, ran in the Republican primaries as a more traditional conservative alternative to Trump before bowing out after key primary losses.
  • Vivek Ramaswamy – Entrepreneur who ran in the GOP primary on an “anti‑woke” and populist message, later ending his campaign and aligning himself with Trump.
  • Chris Christie – Former New Jersey governor who ran as an outspoken Trump critic in the Republican primary but never gained broad support.
  • Tim Scott – South Carolina senator who emphasized an optimistic conservative message before suspending his campaign in late 2023.
  • Asa Hutchinson, Doug Burgum, and others – A series of other Republican governors and former officials briefly contested the GOP nomination but exited as Trump’s dominance became clear.
  • Marianne Williamson – Progressive author who challenged Biden from the left in the Democratic primaries but finished with minimal support and ended her run.

How the race shifted over time

The 2024 campaign had some unusual twists.

  • For most of 2023 and early 2024, the presumptive general‑election matchup was Joe Biden vs. Donald Trump, with primary challenges failing to dislodge either.
  • Biden’s withdrawal in July 2024 and his endorsement of Kamala Harris reshaped the Democratic side and made Harris the new face of the ticket relatively late in the cycle.
  • Independent and third‑party campaigns (Kennedy, West, Stein and others) tried to capitalize on voter frustration with a Biden–Trump rematch and with the two‑party system in general.

Forum-style quick scoop

“So, who was actually on the 2024 ballot?”
Think of it in layers: first the giant early‑season crowd, then the primary survivors, and finally the Election Day lineup where Trump led the Republican ticket, Harris led the Democratic ticket after Biden stepped aside, and a smaller cluster of independent and third‑party candidates tried to break through.

TL;DR:
In 2024, the presidential scene moved from huge primary fields in both parties to a general election centered on Donald Trump for Republicans, Kamala Harris for Democrats after Biden withdrew, and a few notable independent and third‑party candidates like RFK Jr., Cornel West, and Jill Stein.
