Midterms scenarios: will Republicans take the Senate and the House?

A handful of general scenarios could play out on Tuesday, each having huge significance for Biden and Donald Trump

As Americans go to the polls on Tuesday they are voting in what Joe Biden has framed as a vital test for American democracy in the face of a Republican party fielding candidates who buy into the big lie of a stolen 2020 election.

Republicans, meanwhile, have tried to capitalize on widespread economic anxiety in the face of rising inflation as well as stoking culture war themes and fears over crime, often spilling over into racism and intolerance.
