Like many of you, I'm reading the collected anecdotes of high turnout in Democratic urban areas, and then the inevitable stories about said turnout anecdotes from Democratic-leaning publications, and then the Tweets, and then more stories, etc. The point of these anecdotes is convince people who haven't voted that their vote won't be wasted. It's a noble goal.
But privately, senior Democratic officials with access to the boiler room data say that they've seen nothing to indicate that these anecdotes are evidence of a Democratic surge, or will lead to a surprise in the story tonight. That's not to say that there won't be a surprise, just that nothing Democratic officials are seeing actually gives them real confidence that there will be one.
If anything, the early boiler room data makes the Democrats quite nervous.
