California governor race and LA mayor race top Tuesday primaries

Six states vote in primaries Tuesday, led by California's governor’s race—where Xavier Becerra and Tom Steyer vie with Republican Steve Hilton after Eric Swalwell's exit—and a crowded Los Angeles mayoral field including Spencer Pratt facing incumbent Karen Bass and Democrat Nithya Raman; Democrats seek to expand their Senate map with Iowa and Montana open seats, while other California and New Jersey House races are watched for clues ahead of November.
