US President Donald Trump has made a last bid for voters to back the Republican party on the eve of a nationwide election that is seen as a referendum on his presidency.
"Everything we have achieved is at stake tomorrow," he said during a blitz of three final rallies.
The mid-term elections come half way through his four years in office, and will determine how effectively he can govern for the next two years.
Voter turnout is expected to be high.
Some pundits have said that Trump will get destroyed at tomorrow's elections and the Republicans will lose both Houses. Others say the opposite and that Trump will come back firing on all cylinders. What are we to make of it?
I think it will be close, but I'm not sure if either side will be able to claim a decisive lead here. Trump is far too controversial, which for his supporters is great, they like him for that, but for Trump to claim a decisive win, he needs to win over the middle ground. He doesn't "do" middle anything.
