Voting is continuing right across the United States for the 2022 midterm elections.

The Democrats are staring down the barrel of a red wave.

For two years, the party has held the House and the Senate, both of which could flip to the Republican party.

Polls suggest the Republicans will almost certainly take the House, while the the result in the Senate will come down to the wire.

More than 45 million Americans have already had their say in pre-election polling.

All 435 seats in the House are up for grabs, as well as 35 seats in the 100-member Senate, 36 state governorships, three U.S. territory governorships and a large number of city mayorships and local offices.

In a further 37 states, issues including laws on abortion, marijuana and voting rights are also up for a vote.
