Missouri is moving ahead with the Aug. 4 primary under a newly drawn congressional map, even though the map is still being challenged. A court or referendum outcome could later change which districts are used in November, creating possible confusion between the primary and general-election districts. This adds uncertainty to the nomination market because the district lines may still change. It does not clearly favor any candidate, but it could affect how the race is framed and counted.
Missouri officials are using a contested congressional map for the August primary while legal challenges remain unresolved.
Progressives are fired up, but some districts are still backing centrist Democrats in primaries ahead of the November midterms.
