Rep. Cori Bush (D-MO) is far behind a challenger in the Democratic primary for her congressional seat, a new poll suggests.

A poll from Republican polling firm Remington Research Group, for the Missouri Scout, shows Bush trailing St. Louis County Prosecutor Wesley Bell, 50% to 28%, in the Democratic primary. Another 4% said they favored state Sen. Maria Chappelle-Nadal, and 18% were undecided.
