The Democrats have won control of the US Senate, flipping a string of Republican-held seats to take the majority in Congress’ upper chamber. The gains came in states long seen as Republican strongholds, including Texas, Ohio, North Carolina, South Carolina and Georgia.

A win by Democrat Josh Turek over Republican Ashley Hinson in Iowa proved enough to tip the chamber to the Democrats, sealing a night in which the party picked up ground across the map.

Momentum had built earlier in the evening after Roy Cooper flipped an open Senate seat in North Carolina away from the Republicans. Cooper, a former governor of the state, defeated former Republican National Committee chairman Michael Whatley, delivering one of the four net pickups the Democrats needed for a majority.

One of the most prominent victories belonged to James Talarico, who was called as the first Democratic Senator elected in his state since 1988.

The results reversed a Republican advantage in the chamber. Democrats had gone into the night aiming to break the Senate’s Republican hold and recapture the majority, a task that required winning in places the party had struggled to carry in recent cycles. By taking seats in Kansas and Ohio alongside the others, they cleared the threshold they had set, with the party flipping seats in Iowa, Kansas, Ohio, North Carolina, South Carolina and even Texas.

Alongside the Senate, the party was in a strong position to take control of the House as results came in through the evening. Democratic candidates also won races in Georgia and New Hampshire and the outcome landed as a sharp rebuke to President Trump in territory his party had long counted on.
