Calling a state after its polls close doesn't affect the integrity of the voting process one bit. The polls are closed. Not one vote can be affected. Of course if they're wrong they're going to end up with egg on their face when the votes are counted. But the call doesn't affect the count any. Lord knows I'm the last guy to defend Faux, but as long as the polls were closed I don't see any legit reason for the McCain camp's reaction.
Polling and Statistics as well as what counties have reported. For instance. I knew Obama had won a couple of states even when he was way down early simply because i know where each candidate's votes come from.
That was Carter in 1980. Not only did the networks call it, but Carter conceded. I really wish they wouldn't tell those of us out west anything before the polls closed out west, but in today's internet age and chat rooms, I don't know how you stop that flow of information. The rule is that they will not call a state before its polls close.
