So I'm watching C-Span

[Goldeneye]

and the guy is talking about exit polling in the 2004 election. He had a piece of paper which he wrote out on election day at CNN headquarters that had Kerry winning 51% to Bush's 48%, however he notes that he was supposed to be very careful with the data, because it was based on 58% women. So I have a few questions

1. Why would the exit poll companies send out info that hadn't been
reweighted, when it is seemingly very easy to do?

2. The guy is named Stuart Rothenberg. Is he reliable?

3. Did CNN put data that wasn't reweighted up on their site? If so, why would they do that, when they had been warned that the data was unreliable.

4. What are exit polls really used for? If they aren't meant to call races what are they really for?
