What do these numbers mean?
These numbers come from hundreds of state and national polls aggregated by The Huffington Post and made available through their Pollster API. Raw polling numbers are related to — but not the same as — the probabilities that Obama or Romney will win a given state.
Why are there states without data?
The Huffington Post has not made the necessary data for these states available through their api. However, these states would be some of the least interesting to watch — Hawaii, Delaware, and Vermont have consistently supported Obama for months; the others have consistently supported Romney.
