The early polls are trickling in and they all give a win to Joe Biden.
TPM also points out this nugget from the CNN poll:
While a startling 84% said Palin did better than expected, it still wasn't enough for her to clear her basic hurdle tonight: Only 46% said she's qualified to serve as president, up only four points from before the debate. And a clear majority, 53%, say she is not qualified.
Now, these are "snap" polls and draw from a pretty small pool of voters so take all of this with a grain of salt, but they do serve as an early indication of how people felt, and more importantly, help to develop the press narrative
