Yeah, James Carville's Democrats strike again. Treat this as nothing other than an advocacy group poll.
It's basically Democrat trolling the media at the end of the day to show Hillary! is up big. And if that's the best they can come up with in NV, Hillary is in trouble there.
I mean... first of all, YES she is in trouble in NV, we knew that already. Second of all, this corroborates all the +5's and +6's we've seen so far, so while I think this is too optimistic I wouldn't discount it completely, unless this pollster has a really terrible history/methodology
