Democrats eye expanded majority as key Senate and House races remain undecided

Democrats have secured control of both the House and Senate, but several key races remain too close to call as of Thursday, potentially expanding their majority. In Mississippi, Democrat Scott Colom leads Republican incumbent Cindy Hyde-Smith by over 1,100 votes, with counting continuing until November 10. A Colom win would make him the first Black senator from the state since 1875. Alaska's Senate race is also tight, with Democrat Mary Peltola leading Republican Dan Sullivan by just over 600 votes amid controversy over a ballot scheme allegation. House races involving Trump ally Lauren Boebert and others remain undecided, while California's Proposition 40, a proposed billionaires' wealth tax, is trailing in early counts.
