Seems like a massive load of nothing that can be boiled down to this:
Marginally more Democrats than Republicans have already voted. This is consistent with registration data, so means nothing.
We don’t know how people are actively voting.
We don’t know if Democrats or Republicans are more likely to vote early or late or by mail or in person.
We don’t know how Indepedents are voting.
We don’t know jack squat about anything until oh, I don’t know, there’s actually some results.
I don’t mean to slam the people gathering this data; I just mean there’s not much we can do with it.
We suspect that Democrats will just not turn out to vote.
