Suffolk, NBC have clinton up by nine. I question their sampling.
Quinnipac has trump up by 2.
11 point swing, same timeframe? That's most likely due to oversampling of democratic voters.
In short, it's early.
The key on polls, is how they sampled, and how many.
Far too often, polls are taken just for bragging rights, commercials than actual statistical analysis.
If you pay people to produce an answer, they generally hit that mark often.
