If you want to ride an election-night roller coaster, check out the live election forecast on the New York Times's Upshot blog.

The Upshot's final calculations before polls began closing on Tuesday gave Hillary Clinton an 85 percent chance to win the White House. But as early returns streamed in, the odds swung in Donald Trump's favor.

By 10 p.m., Trump had a 63 percent chance to win, according to the Upshot.

Some journalists have been riveted by the real-time updates — and stunned by what they are seeing.

At the same time that the Upshot was calling Trump the favorite, Nate Silver's FiveThirtyEight still considered Clinton the likely winner.

And VoteCastr's battleground projections, published by Slate, forecast Clinton victories in Ohio, Florida, Iowa, Nevada, New Hampshire, Pennsylvania and Wisconsin — very different from what the early returns indicated.

When all the votes are counted, someone is going to have serious bragging rights.
