My election prediction 24 hours before we start getting results: Biden wins handily.

We effectively know the result by 3 AM eastern US time, but it's all but certain early when Biden narrowly carries Florida (~2.5%). Biden wins the national popular vote (not that anyone cares) by ~ 7.2%. Not quite landslide territory, but enough for a very clear result.

The major networks will be giddy, but they won't call the result on election night.

Trump does hold Arizona, but he's unable to replicate his 2016 breakthroughs in MI, WI, or PA (although PA will not be called on election night).

Georgia ultimately goes for Biden, but Texas remains red one more time.

With Florida going for Biden, Trump ends up not doing anything stupid like "declaring" victory, although neither does he give a concession speech on election night.
