Democrats secure Congress, but key races remain undecided

Democrats have secured control of both the House and Senate in the midterm elections, but several key races remain too close to call as of Thursday, including Senate contests in Alaska and Mississippi that could expand their majority. In Mississippi, Democrat Scott Colom leads Republican incumbent Cindy Hyde-Smith by about 1,100 votes, with counting continuing until November 10. In Alaska, Democrat Mary Peltola leads Republican Dan Sullivan by over 600 votes, amid controversy over a third candidate with the same name. House races in Colorado, Tennessee, and Arizona remain undecided, including Trump ally Lauren Boebert trailing in her district. California's Proposition 40, a proposed billionaire wealth tax, faces opposition, while tight mayoral and gubernatorial races in Los Angeles and Kansas are also pending.
