Who will win the Democratic nomination for President in 2028?

TL;DR

Other is the most likely option at 24% because it pools several live candidates and future breakouts. Kamala Harris is the leading individual at 23%, narrowly ahead of Gavin Newsom at 21%. The 2026 midterms, formal entry decisions, and the first credible South Carolina polling will move the forecast most.

Context

The nominee will be the person formally selected at the Democratic convention, scheduled for August 7–10, 2028 (DNC). The party approved South Carolina, Nevada, New Hampshire, New Mexico, Michigan, and Virginia as the six pre-Super Tuesday contests on August 15, 2026 (DNC). None of the named contenders had filed as a 2028 presidential candidate by the cutoff (FEC).

Harris leads the current national average, but these are hypothetical ballot tests of an undeclared field. The ten-poll average covering July 3–August 17 has Harris at 27.6%, Newsom at 16.4%, Buttigieg at 11.6%, Ocasio-Cortez at 9.4%, Mark Kelly at 6.8%, and Shapiro at 6.6% (RealClearPolling). Candidate lists, sample screens, and individual results vary sharply, so those shares are inputs rather than nomination probabilities.

Evidence

The historical backbone is unfavorable to confident early forecasts. Gallup’s complete published series of 12 non-incumbent Democratic contests from 1956 through 2016 found that only four eventual nominees held a sustained national lead from the year before the election. Eight emerged as the lasting leader only after the election year began (Gallup).

That is a 33% early-leader rate in Gallup’s reference class. It is not a direct prior for Harris: she has far greater recognition than Carter, Dukakis, or Bill Clinton had. But the current forecast is even earlier than Gallup’s year-before-election window, so Harris’s lead cannot support anything close to lock status.

The polls do establish a real top tier. Harris leads most recent surveys, yet their spread shows how soft the field is. Echelon’s August 13–17 poll of 483 likely voters had Harris at 18%, Buttigieg at 13%, Newsom at 12%, and AOC at 11%; Emerson’s July 19–20 poll of 1,100 likely voters instead had Buttigieg at 19%, Newsom at 17%, AOC and Ossoff at 13%, and Harris at 8% (RealClearPolling). The Emerson ballot omitted some candidates included elsewhere. I therefore flattened the polling signal rather than translating vote shares directly into win probabilities.

The calendar raises Harris. In an April 21–23 Verasight survey of 864 Democratic and Democratic-leaning adults, she led nationally with 22% and received 49% among Black respondents; Newsom had 15% in both groups, while Buttigieg had 12% overall but 2% among Black respondents (Verasight). The racial subgroup is much smaller than the full sample, so the exact 49% is noisy. The gap is still large enough to show a coalition advantage in South Carolina.

New Hampshire points the other way. A University of New Hampshire poll of 648 likely Democratic primary voters, conducted July 15–20, placed AOC at 22%, Buttigieg at 21%, and Harris at 5% (UNH). A Saint Anselm survey conducted August 17–18 among 1,411 New Hampshire likely voters overall also had Buttigieg leading the Democratic test at 25%, followed by AOC at 17% (Saint Anselm College). Harris has the broadest current national coalition, but Buttigieg and AOC have genuine activist strength in a state built around retail campaigning.

Harris remains my narrow individual favorite. She publicly said on April 10 that she was thinking about another campaign (Reuters). South Carolina gives her a viable route to an early win, and no rival currently matches her measured Black support. Her ceiling is capped by the 2024 loss, uncertainty over whether she runs, and weak enthusiasm reported among former donors, fundraisers, aides, and allies (ABC News).

Newsom is the most likely major contender to run. He has said he will seriously consider the race after the 2026 midterms (Associated Press). His organization has raised more than $1.7 million for 14 state parties and legislative committees from more than 74,000 donors, including over $300,000 for South Carolina Democrats; affiliated committees reported more than $14 million in cash at the end of June (Axios). That network is more predictive than another television appearance. His California record, weaker Black support, and unresolved federal-investigation risk keep him just behind Harris.

Buttigieg has the clearest affirmative statement, saying on August 3 that he was more inclined than not to run (RealClearPolitics). He then made a targeted August 22–23 trip to South Carolina, appearing at a Black church, an NAACP dinner, and a state-party conference (Associated Press). His run probability is high. His nomination probability is lower because the electorate that ended his 2020 campaign now votes first.

Shapiro has the strongest classic dark-horse profile: a battleground-state governorship, executive experience, and a large political operation. His campaign entered 2026 with roughly $30 million available for his Pennsylvania reelection (Associated Press). A decisive win and visible Democratic gains in Pennsylvania would strengthen his electability case. Until then, low national recognition and competition from Newsom, Buttigieg, Kelly, and Beshear limit him to 10%.

AOC owns the clearest progressive lane and has demonstrated early-state strength. She has also left open both a presidential campaign and a 2028 Senate challenge in New York (Axios). That fork is the main reason she remains below Buttigieg and Shapiro despite a high upside if she runs. South Carolina first is also less favorable to her current coalition than a New Hampshire-first calendar.

Ossoff receives only 2%. His national profile and online following have risen, but he has repeatedly said that he has zero interest in a 2028 campaign and called the speculation fantasy football (Atlanta Journal-Constitution). Those denials are not binding, especially during a Senate reelection campaign, but they are stronger evidence than viral clips or a single favorable poll. Whitmer receives 1% because she first said she would not run, then softened that to never say never on the same day (Associated Press). Her visible preparation remains minimal.

Other deserves the largest single allocation. Kelly already polls at 6.8% nationally and says he is undecided (Semafor). Beshear is active in South Carolina and speaks openly about how the new calendar fits a Southern, pragmatic candidacy (CBS News). Pritzker has visited early states and built a national political network while leaving the door open (Time). Booker, Wes Moore, Raphael Warnock, Ruben Gallego, Ro Khanna, Chris Murphy, and an unforeseen post-midterm breakout add several smaller paths (Reuters).

I combined three views: current polling and coalition strength; probability of entering plus organization; and a historical-disruption view that allows late entrants and early-state momentum to overturn today’s order. Conceptually, each named candidate is estimated as $P(\text{runs})\times P(\text{nominee}\mid\text{runs})$. The high historical variance keeps Harris and Newsom near 20%, while the depth of the unlisted field keeps Other at 24%.

What's non-obvious

Newsom’s state-party fundraising is the best weak signal in the race. Polling can move after one interview or a changed ballot. Raising money for South Carolina, Nevada, New Hampshire, and Michigan creates staff capacity, goodwill, donor data, and relationships that can survive a bad news cycle (Axios). That is why Newsom remains close to Harris despite trailing her by more than 11 points in the national average.

The other easy mistake is treating Other as dead weight or treating Ossoff’s online attention as evidence of likely entry. Other contains at least three plausible candidates already polling or organizing at meaningful levels. Ossoff is one person who keeps denying that he wants the job. Aggregation makes the former more likely than the latter.

Uncertainties

The largest missing piece is a high-quality South Carolina poll with adequate Black-voter, age, education, and ideology samples. Nevada, New Mexico, Michigan, and Virginia also lack comparable public polling. New Hampshire may try to move ahead of South Carolina under its state-law requirement to hold the first presidential primary, so the official order is not guaranteed to survive unchanged (The Atlantic).

The November 2026 results will alter the field. Shapiro’s margin and Pennsylvania coattails will test his electability pitch. Ossoff’s Georgia result will determine whether his current denials remain credible after the election. Formal declarations, early-state staff hires, major endorsements, donor retention for Harris, the status of the Newsom investigation, and AOC’s president-versus-Senate choice would close most of the remaining gap.
