Photos of primary races across the US as candidates compete to get on the ballots for the midterms

Progressive city council member Nithya Raman has advanced to a November runoff against Los Angeles Mayor Karen Bass, setting up an unexpected matchup between two Democrats and former political allies to run the struggling city of nearly 4 million. The outcome means Spencer Pratt, a Republican and former reality television personality from “The Hills,” is out of the running. Raman made a last-minute entry into the race, after she had endorsed Bass for reelection. The race also has historical markers. Bass is the first Black woman to hold the post, and Raman could be the first South Asian woman in the job.
