the more women turn out in the swing states the better for Harris, same for younger men and Trump.

Polling companies, having adjusted for mistakes they've made in the past, are now overestimating the level of support for Trump.

Harris is leading by a long way in votes cast so far, but this is going to swing drastically the other way on the day.

There is little to no chance of the rust belt states that flipped to Trump in 2016 and back to Biden in 2020 going red again this time round and this alone will virtually guarantee a Harris victory.

Trump's going to win virtually all the swing states.

In short, nobody knows. Too many variables on the day - I don't think any outcome from a small to comfortable win for either would be a big surprise.

I'd be pretty apprehensive whatever the result if I were a US resident. Bad enough watching all this unfold from afar.
