I am currently updating a tool I wrote which can help to make projections on election night. I used it during the primaries and it simply takes the current vote tallies per county, along with the “% precincts counted” and then extrapolates each county individually to arrive at the totals for the whole state. This can be super helpful in cases where a big city may only have 10% of the votes counted whereas the rest of the state might already be 90% done – in which case the overall numbers will have a big skew away from the city voting patterns.
Anyway, subscribe to my feed and I’ll post a link here when it is ready. And, obviously it will only be useful for a couple hours on Nov 4th – less than 20 days away!
