I agree the numbers are small to draw any conclusions right now, but if I’m reading some other data correctly, Unaffiliated voters have been pretty 50/50 for Rs and Ds.
I don't believe they tally the actual votes until election day.
The U's are the most likely to be swayed from one cycle to the next, and I'm not sure there's any merit in trying to guess how they'll line up across the state.
