Which state will vote first in the 2028 Democratic presidential primary?
New Hampshire is still the most likely first Democratic contest in 2028, but the market appears to be pricing it like an almost certain outcome. I think the state’s structural advantages are real, yet the combination of DNC rulemaking, calendar negotiation, and possible changes in state/party compliance leaves meaningful room for an alternative first contest.
Analysis
New Hampshire has the strongest institutional claim to being first: its state law, long-standing political identity, and the fact that it has repeatedly been willing to schedule and administer an early primary even when national Democrats object. That makes it the natural default favorite if you are simply asking which state most likely ends up holding the earliest contest. Iowa’s position has weakened substantially after recent cycles, and Nevada has never had the same durability as New Hampshire’s early-primary machinery. South Carolina is the most credible challenger because the DNC has shown a willingness to elevate it, but that still depends on party decisions holding through 2028 and on whether New Hampshire again insists on going first anyway.
The main reason not to assign an even higher probability is that this market is not asking whether New Hampshire is historically favored; it is asking what will actually be reported as the earliest 2028 Democratic contest among the states before the deadline. That outcome is sensitive to DNC calendar design, state law enforcement choices, and whether a sanctioned party-run contest in another state gets recognized as first. The 2024 cycle showed that the national party can and will reshuffle the order, and New Hampshire can respond by moving ahead regardless, which creates a real possibility of ambiguity or a different state being reported first depending on how the rules are implemented in 2028.
Compared with the current market price of 87%, I think New Hampshire is overpriced as a near-lock. It remains the clear leader, but not to the point where the market should be assigning only a low-teens chance to every other state combined. The most plausible mispricing is underestimating how often Democratic leadership, state-party decisions, or formal calendar changes can move South Carolina or another contest ahead of New Hampshire, even if New Hampshire still tries to preserve its first-in-the-nation status.
Arguments
For
- New Hampshire has the deepest precedent and strongest legal-political infrastructure for going first.
- Recent history shows New Hampshire is willing to preserve its first-place status even when the national party resists.
Against
- The Democratic Party has already demonstrated a willingness to reorder the primary lineup away from New Hampshire.
- South Carolina is the strongest alternative because it has become the party’s preferred early anchor state.
Key drivers
- New Hampshire’s state law and political tradition strongly favor an early first contest.
- DNC control over the 2028 calendar could still elevate another state if New Hampshire is not sanctioned or aligned.
Risk factors
- A 2028 DNC-approved calendar could again prioritize South Carolina or another state ahead of New Hampshire.
- If New Hampshire’s contest timing becomes disputed or nonstandard, source agencies may report a different official earliest contest.
Scenarios
Best case
New Hampshire schedules and administers the earliest recognized Democratic contest again, with no other state successfully moving ahead of it.
Most likely
New Hampshire still ends up first, but the path is not automatic and depends on the 2028 rules, with South Carolina the main threat if party leaders enforce a different order.
Worst case
The DNC calendar or state-party arrangements make South Carolina or another state the first clearly reported Democratic contest, and New Hampshire is not recognized as earliest.

Which agencies will Trump eliminate?
AI78%MKT26%Edge+52Hidden GemI think Yes is substantially more likely than the market implies, because multiple reports indicate USAID has already been dismantled in practice. The main uncertainty is whether the market resolves on formal legal abolition or on operational elimination, but the balance of evidence still favors Yes.
