Americans vote on Tuesday (3) in the midterm elections, the midterms, after months of campaigning and billions of dollars spent. g1 published a BBC analysis with three possible outcomes for the count.
The latest polls indicate a Democratic advantage, but the analysis notes that surveys are not always right. Historically, these elections favor the opposition party, and the current scenario combines an unpopular president, a war against Iran that raised the cost of living and controversial policies, such as the aggressive crackdown on immigration.
In the first scenario, a big Democratic wave, the party would comfortably surpass the 218 seats needed in the House and could win in unlikely Senate states, such as Texas, which has not elected a Democrat in a generation, or Kansas, in almost a century.
In that case, Democrats would have a cushion of one or two seats in the Senate, which would avoid complications such as a possible Republican legal challenge in Alaska, where a judge rejected a Trump administration suit over the dispute between two candidates with the same name.
The other two scenarios, according to the BBC, would be a more modest Democratic advance and a Republican resilience that surprises the polls.
