Will the margin of victory for Cori Bush in the 2026 MO-01 Democratic primary be between 6% and 9%?

✨ The field is virtually nonexistent: only two candidates register at 1% each, and no one has broken 5%, making this the most open Democratic nomination race in modern history. The single biggest recent shift is the DNC's decision to put South Carolina first in the 2028 primary calendar (Axios, Jul 25), which could reshape candidate strategies and favor a different type of contender.

✨ The field is moderately concentrated with Labour leading at 36%, but Reform UK and Conservative are close; the biggest recent shift is Reform UK overtaking the Conservatives for second place, as seen in the stated odds, though no headline directly explains this.

Yes ≈ 53% chance

✨ The Republican nomination field is exceptionally fragmented, with no candidate above 5% and the top three sum to just 1% — a sign that the race is truly wide open and still in its earliest jockeying phase, despite a recent poll placing Senator JD Vance near the top of a generic primary ballot (USA Today, Jul 23).

✨ Despite Newsom's commanding lead, the field is far from settled: the 20% 'Other' share and AOC/Ossoff's recent gains per Action Network (Jul 8) suggest a pool of anti-Newsom sentiment waiting for a viable alternative.
