6 Races to Watch in Georgia, Alabama, Oklahoma & D.C.

Quick summary:

• Republicans have competitive primary runoffs to decide U.S. Senate nominees in Georgia and Alabama. The Georgia winner will face Democratic Sen. Jon Ossoff in the fall, while the Alabama victor will be a heavy favorite to be the solidly Republican state’s next senator.

• The GOP also has very close gubernatorial nomination contests in Georgia and Oklahoma. In Georgia, the primary runoff looks to be on a knife’s edge, while the Oklahoma primary looks certain to go to a runoff — but which two candidates will advance?

• Democrats have a competitive primary for mayor in the District of Columbia. The contest has two leading candidates, with the winner almost certain to become the dark-blue city’s next leader.

Three states and the District of Columbia hold primaries or primary runoffs on Tuesday. The most-watched contests are likely the runoff elections in Alabama and Georgia, where Republicans in both states must decide their nominees for U.S. Senate and/or governor. But Oklahoma also holds its regular primary for state and federal offices, including governor, while D.C. Democrats will nominate the city’s likely next mayor.
