Key US Senate results: Democrats wrest North and South Carolina from the Republicans

Initial results from Tuesday's US midterm elections show Democrats making significant gains by winning Senate seats in North and South Carolina. These victories come as the party seeks to flip control of the Senate from Republican hands.

The Democratic party needed to secure a net gain of four seats to win control of the Senate. Along with their surprise wins in both Carolinas, they successfully held onto their existing seats in Georgia and New Hampshire.

These results mark a notable shift in political landscape, as North and South Carolina have traditionally been Republican strongholds. The outcome could significantly impact the balance of power in the Senate during the remainder of the current congressional term.

The final Senate control will depend on results from remaining races still being counted across the country. Democrats are now positioned to potentially achieve their goal of gaining the four additional seats needed for majority control.
