A key US midterm election result in the state of Nevada has left Democrats in control of the Senate – so far they have 50 seats compared to the Republicans’ 49. The final spot to be settled is from Georgia where neither major party candidate got 50% or more votes last week, so there’s a run-off election on 6 December. Even if the Republicans and Democrats get 50 Senate seats each (which is where it was before the midterms…), the Democrats will retain control with Vice President Kamala Harris able to cast a tie-breaking vote. Maintaining control of the Senate is a big deal for President Joe Biden because so much of the political agenda is set there, including the appointment of US Supreme Court judges. As for the House of Representatives, the votes are still being counted, but experts still think a Republican win is likely.
