Democrats gained control of the House and Republicans expanded their majority in the Senate, but the final numbers remained uncertain early Wednesday morning as several races remained undecided in each chamber.
Democrats notched key wins in suburban districts from Virginia to Colorado to Florida and were projected to win more than the 23 seats they need to gain control of the House. Several races remained too close to call.
In the Senate, Republicans expanded their majority after Democratic incumbents lost seats in Indiana, North Dakota and Missouri and GOP senators won closely watched races in Texas and Tennessee. Still undecided were key races in Florida, Arizona and Montana.
In governor’s races, Democrats scored a surprising win in Kansas, while in Florida the Republican beat back a challenge in one of the most closely watched races in the country. A winner still hasn’t been declared in gubernatorial contests in Georgia and Wisconsin.
