There is no doubt that early voting statistics are bringing a lot of good news for Democrats in North Carolina.
I would caution against getting too hyper about it. For instance blacks have so far made up almost 29% of the electorate. It's important to keep in mind that during the primary 40% of early Democratic primary voters were black, but they only ended up comprising 34% of the total electorate when you factored in the election day voters. These early figures reflect a definite enthusiasm gap. It's also a lot easier to vote early in larger counties where a ton of sites are open at a wide variety of hours- those sorts of places tend to be more Democratic. Both those things said, the news is very good.
On the North Carolina tracking poll this week we'll ask people whether they've voted yet or not, and we will dig deep into those numbers on Monday to try to get a picture of what sort of electorate we can expect going into election day as well as whatever lessons we can learn about the voting preferences of those who have already cast their ballots- down ballot fatigue, ticket splitting, etc.
We're also going to have new polls next week for NC-8 and Wake County, each of which should give us a more detailed view of what's happening in some key parts of the state.
