The Republican Party has won control of the Senate in the US mid-term elections, increasing its power in the final two years of Barack Obama's presidency, reports GHN based on BBC.
The party took Arkansas, Colorado, Iowa, Montana, North Carolina, South Dakota and West Virginia.
And it is expected to post more gains as votes are counted in other states.
The party is also set to strengthen its majority in the lower House of Representatives.
Throughout the campaign, Republicans focused on voter dissatisfaction with Mr Obama, describing the vote as a referendum on his presidency.
As the first results came in late on Tuesday, it became clear they had made convincing gains in the roughly one-third of the 100 Senate seats up for election.
With the votes still being counted in many states, the Republican Party appears easily to have won the six seats it needed to win control of the Senate.
In addition to seats the party won from the Democrats, the Republicans retained seats in Alabama, Georgia, Kansas, Maine, Mississippi, Nebraska, Oklahoma, South Carolina and Tennessee.
One of the key early results came in Kentucky, where Republican Senate Minority Leader Mitch McConnell fended off Democrat Alison Lundergan Grimes
Mr McConnell will now become the Senate majority leader, giving him control over the chamber's legislative agenda and floor proceedings.
"It wasn't about me or my opponent," he told supporters as he declared victory, "it was about a government that people can no longer trust."
As well as taking the Senate, the Republicans are projected to increase their majority in the House of Representatives, where all 435 members were up for re-election.
They also made gains among the thirty-six governorships up for re-election.
Republican governors survived tough re-election battles in Florida and Wisconsin.
In two results that illustrate the breadth of the Republican sweep, the party's candidates won in Maryland and Massachusetts, two of the most Democratic-friendly states in the nation.
