Fueled by voter frustration directed at the Trump administration, Democrats secured majorities in both chambers of Congress. According to updates published Friday morning, the party has claimed a minimum of 253 seats in the House of Representatives and at least 54 seats in the Senate, marking the largest Democratic majorities since the early years of the Obama administration.

Close Races Shape Final Majority Margins

While the broader control of Congress is settled, outcomes across approximately two dozen House seats and two vital Senate races—located in Alaska and Mississippi—remained uncalled. The competitive contest in Mississippi drew particular attention, introducing the potential for the state to elect its first Democratic senator in 44 years. In that race, a Democratic district attorney held a narrow lead of 1,813 votes over incumbent Republican Senator Cindy Hyde-Smith as of Thursday afternoon.

With votes still being tallied in the remaining undecided districts, the precise size of the incoming Democratic majorities in the House and Senate hangs in the balance.
