Will anyone win every 2028 Democratic primary and caucus?

If one candidate wins every 2028 Democratic presidential primary and caucus in the states and the District of Columbia held before Sep 1, 2028, then the market resolves to Yes. The qualifying contests are the 2028 Democratic presidential primaries and caucuses held before Sep 1, 2028 in each U.S. state and in the District of Columbia. For each state, the contest is the statewide primary or caucus that allocates the most Democratic national convention delegates from that state (the earlier one if two allocate the same number); in the District of Columbia, it is the citywide primary or caucus. For New Hampshire, the contest is the Democratic presidential primary conducted by the New Hampshire Secretary of State, and for Iowa it is the first statewide presidential preference vote the Iowa Democratic Party conducts that reports a statewide count of votes for candidates, whether or not the Democratic National Committee recognizes either one. A candidate wins a contest by receiving the most votes in its final round of counting, not delegates or state delegate equivalents. "Uncommitted" and similar ballot options are not candidates. Projections and preliminary results do NOT count; only official results do. If a contest's official results name no single winner, that contest has no winner. The following are not qualifying contests and do NOT affect the outcome: A contest that is not held before Sep 1, 2028 A contest whose official results report no statewide vote count A contest in a U.S. territory The number is 1 if one candidate wins every qualifying contest, and 0 otherwise.
