What the US midterm elections mean for the rest of the world

Voting is underway in crucial midterm elections in the US.
President Joe Biden says a win for the Republicans would threaten democracy. Former president Donald Trump hints he's preparing a comeback.
The vote will determine if Democrats lose control of Congress
and with it their ability to push ahead with President Joe Biden's agenda for the next two years.

Republicans seem set to do well in the vote, after focusing on the economy in the campaign. But more than half of Republican candidates say they believe the unfounded claim that Donald Trump won the 2020 election.
This is raising fears among democrats that the very future of democracy could be at stake in this election
