Exit polls

I don't care if they release exit poll data early. All it is, really, is another poll that happens to come out on election day. If you thought releasing that early would influence whether or not people will vote, then you shouldn't release any polls at all.  The embargo on this data is really just a self-important grand gesture on the media's part.  Yes, their behavior can influence elections. But no, this isn't the way that happens.

Besides, if people can turn out to vote for President under the electoral college system, they can also fool themselves into believing it matters whether or not they vote after a sample of some voters who have already voted talk to the press.
