US Elections: Congress Control Remains in Balance after medium-term elections

Republicans are the favorite to win the House of Representatives, but the Senate's struggle is on edge of the knife, the BBC writes.

The Democrats won a key seat in the Senate in Pennsylvania and the results of several other close races have not yet been announced, as exit polls suggest the economy and inflation were the biggest concerns for voters.

Although President Joe Biden, a Democrat, is not on the ballot, the mid-election will form the fate of his agenda.

If the Democrats lose control of the Chamber or Senate, the republics will be able to block its plans.

Former President Donald Trump, who is expected to announce he will run for president in 2017, has faced the failure of some of his candidates.

In one of the most popular competitions in the Senate, left-wing Democrat John Fetterman, who is recovering from a stroke, beat the famous doctor Mehmet Oz backed by Trump in Pennsylvania.

Another critical race for the Senate, between the Democrat Raphael Warock and Republican rival Herschel Walker in Georgia, could end up in a runoff after four weeks if none of the candidates get more than 50% of the vote -- a possibility that seems possible.

Meanwhile, the Democrat candidate in Georgia, Stacey Abrams, accepted the race to Republican Governor Brian Kemp.

The elections were held smoothly throughout the country, abortion was the main concern for democratic voters, while Republicans and independents praised inflation as their main issue.
