According to SOS, Mac is up 2.3% in Ohio. This is 2000 all over again. Wait for the vote count before making calls. http://vote.sos.state.oh.us/pls/enrpublic/f?p=130:14:0
Calling the vote is a completely different technique than polling exit or otherwise. I did a bit of it for channel 2 in NYC when i was in college. Without computers we could look at returns from a few precincts and by comparing turnout and actual returns we could make a call in the vote that nine times out of ten was dead on.
The Pa call was way too early, but 15% in Ohio, if they are from predictive precincts should produce a tragic but correct result. If I'm wrong I'll be ecstatic, but my email is clicking away every few minutes with Channel 4 updates on what state has been called for obama. I'm turning off the sound so i don't hear them.
