I'll bet you could get each state's official SOS results relatively easily. However, "calling" the election depends on more than just the official SOS reports. CNN will call things when their exit polls show one thing and then the early rounds of official results confirm them.

I think you'd need more granularity than SOS websites provide. They tend to be county by county, and you really need precinct by precinct.

I think county by county results would be enough to do a reasonable prediction but I don't think SOS websites are updated with those results in anything close to real time on election night.
