I’ve fixed it to handle the fact that states are simply “called” on election night, with no estimate of the margin of victory given. Instead the original projection is shown. So if Ohio is the first state called, and it goes to Obama as Mr Silver currently predicts, the top of the map might look like this:
If however it goes to Romney, the bottom of the map will look like this:
I’ll try to keep the map up to date until I go to bed – hopefully the outcome of the election will be obvious by then!
