Who looks likely to win?
So far the Senate race looks even closer than the presidential election. Democrats were favoured by forecasters to win the presidency and keep the House majority, but the future of the Senate is far less certain.
As both parties currently hold 48 seats each, it is now too close to call the results of the Senate.
With more than 98 per cent of results currently announced in Georgia, Mr Biden is narrowly poised to win the state and will be the first Democrat to do so since Clinton in 1992.
But what would a Biden victory in Georgia mean for the Senate?
A blue Georgia would make it likely that the state would have to hold two runoffs for its seats in the Senate in January, and Republicans power in the chamber is possibly under threat.
Recent results from this morning, November 6, saw the Georgian county of Clayton narrowed the lead of Republican Senator David Perdue, over the Democratic opposition Jon Ossoff. Senator Perdue claimed 49.8 per cent of the vote, meaning he was 0.2 per cent short of the 50 per cent essential to win the race. Meanwhile, on the morning of November 6, the Democrats gained another single in the Senate, leading to the current 48-to-48 seat tie.
The Republicans looked likely to win a majority as they held on to key states such as Iowa, Montana and South Carolina. They had also managed to win back the Senate seat in Alabama from the Democrats.
The Democrats have managed to flip senate seats in Colorado and Arizona, though, they still currently fall short of the 51 seats needed to win a majority.
The appointment of Amy Coney Barrett as Supreme Court judge could also have an impact yet to be reflected by analysis.
What are the key races to watch?
As the struggle for the Senate is so unpredictably narrow, there are several vital races which might just swing the outcome of the 2020 Senate election.
Firstly, California’s 21st Congressional District is an important race, as Democrat, TJ Cox’s ability to maintain his seat in the previously Republican-ruled area of Southern California will offer an indication of the strength of the blue’s power overall. Just two years ago, in 2018, Cox defeated the Republican candidate, David Valadao, by less than one point, so the world will undoubtedly watch this re-battle in anticipation.
The race for New York’s 11th Congressional District is another telling sign of Mr Trump or Mr Biden’s success, as, despite New York’s reputation as a Democratic state, Republican Nicole Malliotakis is putting up a tough fight for this Staten Island borough with a previously Republican stronghold.
The battle between Xochitl Torres Small, a Democratic Congresswoman, and Republican Yvette Herrell, for the 2nd Congressional District of New Mexico, was one to watch and turned out to be an exceptionally close race. The Democrats claimed the district by as little as 4,000 votes in 2018. In Republican Herrell claimed this win.
What time do the results come out?
Results in the neck-and-neck race could still take a few days.
Mitch McConnell, the Senate majority leader, has been re-elected, according to AP. Polls suggest Mr McConnell has seen off the challenge of Democrat Amy McGrath.
But it remains to be seen what kind of job Mr Connell will be going back to in January if the Democrats flip the Senate.
