Voters head to the polls in several states today for primary elections. California faces a crowded field in the race to replace outgoing Governor Gavin Newsom. Under the state’s “jungle primary” system, the two candidates who receive the most votes today will advance to the general election, regardless of party. In Los Angeles, 13 candidates are looking to unseat incumbent Mayor Karen Bass. Polls show Bass in a close race with City Councilmember Nithya Raman and reality TV personality Spencer Pratt. In Iowa, Republicans and Democrats are selecting candidates to replace Republican Senator Joni Ernst, who’s retiring. There are also primary elections in Montana, New Jersey, New Mexico and South Dakota.
