AP Decision Notes: What to expect in Washington state's primary

On Tuesday, primary elections are being held across multiple U.S. states, including Washington, Kansas, Michigan, and Missouri, featuring high-stakes congressional and gubernatorial contests. In Washington state, nine contenders are competing in a hotly contested primary for two spots on the November general election ballot for one of the nation's most closely watched congressional seats, while voters statewide select finalists for various offices.

Simultaneously, primaries in other states are shaping the political landscape for the upcoming general election. Kansas Republicans are working to narrow a crowded field for governor to reclaim the state's top office after eight years of Democratic rule, alongside competitive Democratic gubernatorial primaries. In Michigan, voters are deciding a competitive Democratic U.S. Senate primary that has implications for control of the chamber and tests progressive political clout. Meanwhile, a Missouri Democratic primary features a rematch between a St. Louis-area congressman and the former congresswoman he ousted, drawing attention from a powerful pro-Israel organization.
